Can 1000000 Earths fit in the Sun?
How many Earths can fit in the Sun? Though our Sun is an average-sized star, it is the largest object in our Solar System. accounts for 99.8% of our Solar System’s mass, so the mass of all the combined makes up just 0.2% of the Sun’s mass. The answer to the question how many Earths can fit in the Sun depends on how you measure, for example, by mass, volume, or diameter. An image of the Sun captured by NASA’s Solar Dynamics Observatory. Credit: NASA/SDO The Sun’s mass is 1,988,500×10^24 kg, and Earth’s is 5.9724 x10^24 kg, so one Sun equals about 333,000 Earth masses. By volume, the Sun is 1,412,000 x10^12 km^3, and Earth is 1.083 x10^12 km^3, so it would take 1.3 million Earths to fill the Sun (assuming the Earth spheres are squishy and pack in with no gaps!) The Sun’s diameter is 1,392,000 km (864,000 miles), and Earth’s is 12,742 km (7,917 miles), so Earth could line up 109 times across the face of the Sun.
The surface area of the Sun is 12,000 times that of the Earth’s What about the biggest and smallest planets in our Solar System? How many of them could fit in the Sun?, the largest planet, has a mass of 1,900×10^24 kg, 318 times that of the Earth, and would fit 1,000 times into the Sun. is the smallest of our planets, with a mass of just 0.330×10^24 kg, so you would need 21.2 million Mercurys to fill the Sun.
Dwarf planet Pluto has just 1% of the mass of Earth, so more than 200 million Plutos are equal to the Sun’s mass. Our Moon is 400 times smaller than the Sun and 27 million times less massive. You would need 64.3 million Moons to equal the Sun. : How many Earths can fit in the Sun?
How many moons can fit in the Sun?
If the Sun was hollow, it would hold approximately 64.3 million moons! Our Sun is huge, but it isn’t the most massive star. Scientists estimate that about 10 percent of known stars are more massive than our Sun.
How many moons can fit in Earth?
Answer and Explanation: The Earth is significantly larger than the moon so around 50 moons would fit in the Earth. The volume of the Earth is 260 billion cubic miles. The volume of the moon is 5.25 billion cubic miles.
How many suns can fit into Stephenson 2 18?
Stephenson 2-18 (the largest known Star) – About 8 million Suns can fit inside Stephenson 2-18. TON 618 (the largest known Black Hole) – About 10 to the 33th Stephensons 2-18 can fit inside TON 618.
Is the Sun 1.3 million times bigger than Earth?
The Sun is 864,400 miles (1,391,000 kilometers) across. This is about 109 times the diameter of Earth. The Sun weighs about 333,000 times as much as Earth. It is so large that about 1,300,000 planet Earths can fit inside of it.
What is the biggest star?
- Science & Astronomy
The biggest star in the universe makes our sun look tiny speck. (Image credit: dottedhippo via Getty Images) The biggest star in the universe (that we know of), UY Scuti is a variable hypergiant with a radius around 1,700 times larger than the radius of the sun.
To put that in perspective, the volume of almost 5 billion suns could fit inside a sphere the size of UY Scuti. Our sun is enormous — more than a million Earths could fit inside of it. But on a stellar scale, it could be swallowed up by about half of all stars observed so far — especially stars like UY Scuti.

Can Earth have 3 moons?
After more than half a century of speculation, it has now been confirmed that Earth has two dust ‘moons’ orbiting it which are nine times wider than our planet. – Scientists discovered two extra moons of Earth apart from the one we have known for so long. Earth doesn’t have just one moon, it has three. The existence of the two extra ‘moons’ was hotly debated for over 50 years but as per a recent National Geographic report, Hungarian astronomers and physicists have finally provided enough data to confirm that our moon has at least two other companions – made entirely of dust.
Is the Sun 40 times bigger than the moon?
5. The Sun and the Moon are not the same size – From Earth, both the Sun and the Moon look about same size. In fact the Moon is 400 times smaller than the Sun, but also 400 times closer to Earth.
Do planets lose moons?
As the planet approaches the star, the star’s gravitational sphere of influence encroaches on the planet’s, ripping away the three outermost moons and hurling them into elongated orbits around the star. The innermost moon suffers the worst fate: it crashes into the planet.
Does Earth have 1 or 2 moons?
Introduction Moons – also called natural satellites – come in many shapes, sizes and types. They are generally solid bodies, and few have atmospheres. Most planetary moons probably formed out the discs of gas and dust circulating around planets in the early solar system.
- There are hundreds of moons in our solar system – even asteroids have been found to have small companion moons.
- Of the terrestrial (rocky) planets of the inner solar system, neither Mercury nor Venus have any moons at all, Earth has one and Mars has its two small moons.
- In the outer solar system, the gas giants Jupiter and Saturn and the ice giants Uranus and Neptune have dozens of moons.
As these planets grew in the early solar system, they were able to capture smaller objects with their large gravitational fields. How Moons Get Their Names
How many Plutos could fit in Earth?
There are 5 moons orbiting Pluto. Charon is the largest of the lot and is about half as big as Pluto. Pluto itself is very small compared to the Earth — you can fit 170 Plutos inside our planet!
How cold is it on moon?
Taking the Moon’s Temperature Daytime temperatures near the lunar equator reach a boiling 250 degrees Fahrenheit (120° C, 400 K), while nighttime temperatures get to a chilly -208 degrees Fahrenheit (-130° C, 140 K). The Moon’s poles are even colder.
Can you have 2 suns?
What If We Had Two Suns? “A long time ago in a galaxy far, far away” isn’t just the opening of a Star Wars movie anymore. Astronomers have discovered planets that orbit two (and in some cases more than two) suns, making sunsets, such as the one that occurs on Luke Skywalker’s home planet, Tatooine, a beautiful, double-orbed event every day.
- With the discovery of these circumbinary — the scientific term for a planet that orbits two stars — scientists have begun to speculate about what Earth would be like if we had two suns.
- In fact, one scientist has even suggested that we already live in a solar system with two stars — the biggie we see in the sky on cloudless days and a smaller, dwarf star companion called Nemesis, though this theory is not widely accepted,
For our purposes, we’ll assume that we don’t have a second sun named Nemesis in our solar system because if we did, this question would already be answered. So pull up a lounge chair, grab a glass of sweet tea and enjoy the thought of those romantic double sunsets — because the rest of the story isn’t nearly as pretty.
Epler-16b is the first circumbinary planet to be discovered. Astronomers say it’s extremely cold on 16b, so if you’re planning to enjoy that sunset, you might want to grab a parka. If Earth had developed similarly to Kepler-16b — around two dimmer stars, rather than around our one bright sun — we’d be even colder than 16b’s minus 100 degrees Fahrenheit (minus 73 degrees Celsius).
All on our planet would be frozen, and no life would have formed thanks, also, in part to Earth being farther from the sun than 16b is to its star system, Other scientists suggest that day and night would have completely different meanings on an Earth with two suns.
- When both suns were up, days would be much brighter.
- Nights would be different too because the suns would sometimes set at different times,
- Still others suggest that the number of eclipses would increase as one sun moved in front of the other, maybe as often as once a week or so.
- And depending on the axis of rotation of our Earth in relation to these two suns, the seasons might change much more rapidly,
Sounds like an Earth with two suns wouldn’t be nearly as livable as Tatooine — even without the Sand People. So, if you need a double sun fix, your best bet is probably to enjoy the series one more time. : What If We Had Two Suns?
Is it possible to have 3 suns?
Having just one star in our solar system makes us an outlier in our galaxy. However, while most solar systems in the Milky Way have two stars, astronomers have now found another outlier- a solar system with three. The system, known as KOI-5, is located in the constellation of Cygnus.
It was first discovered via observations of an exoplanet, known as KOI-5Ab, over a decade ago. Due to its complicated nature in what seemed to be a multi-star system, however, it was largely overlooked by astronomers in favor of easier-to-study single-star system planets. Nevertheless, some researchers continued to use ground-based telescopes, including the Palomar Observatory, the WM Keck Observatory, and the Gemini North telescope to study KOI-5.
By 2014, they found that it had two companion stars- KOI-5B and KOI-5C. However, they also noticed that these three stars alone could not account for an observed dip in starlight in the system. It was only in 2018 that, using Kepler’s successor TESS, researchers found an answer for why this dip in starlight occurred- an exoplanet orbiting KOI-5A.
- Analyzing previous data, they were able to confirm that this exoplanet was the earlier detected and overlooked KOI-5Ab, and that it orbited at least one of the stars in the system at a skewed angle.
- Delving deeper, the researchers were able to deduce that KOI-5Ab is likely a gas planet around seven times the mass of Earth.
It likely has a five-day orbit of KOI-5A, and in turn, an orbital period of KOI-5B of around 30 years. KOI-5C is further out. As such, standing on KOI-5Ab, KOI-5A would dominate the sky, whereas KOI-5B would look similar to our Sun, and KOI-5C would appear as a very bright star in the distance.
The researchers also noted that KOI-5Ab has a misaligned orbit relative to KOI-5A and KOI-5B. Under normal circumstances, it would have been aligned on the same plane, like the planets of our Solar system around the Sun’s equator. However, it instead sits on a tilt of 50 degrees. As such, they suppose that KOI-5B may have gravitationally skewed the exoplanet’s orbit, kicking it out of alignment while in formation.
“We still have a lot of questions about how and when planets can form in multiple-star systems and how their properties compare to planets in single-star systems,” says David Ciardi, chief scientist at NASA’s Exoplanet Science Institute. “By studying this system in greater detail, perhaps we can gain insight into how the Universe makes planets.” Sources: NASA, Science Alert Other Annie Lennon is a writer whose work also appears in Medical News Today, Psych Central, Psychology Today, and other outlets.

What is the smallest star?
The largest and the smallest known stars in the universe – Phil Massey, an astronomer at the Lowell Observatory in Flagstaff, Arizona with LiveScience to share these nuggets of information. But before we dive into it, we must understand that largest is a vague term.
- A star either be largest in terms of mass or size.
- A heavy star is usually not very large because the weight holds down the particle closer and a voluminous star usually tends to expand and drop mass.
- Massey explained that the largest star in terms of mass is R136a1.
- Located roughly 60,000 light-years from, this star is about 30-40 times the size of our Sun.
Interestingly, this star is also very young at about one million years. In comparison, the Sun is 4.5 billion years old. In a few billion years’ time, R136a1 could burn through its supply of hydrogen and begin expanding and can become the largest star in terms of size, however, at the moment that title is held by another.
UY Scuti is a hypergiant star that is about 1,700 times larger than the Sun. For reference, imagine a marble next to a sphere of the size of Qutub Minar. That’s the difference in their size. The star was discovered in 2013. According to Massey, if this star replaced the Sun at the center of the solar system, all inner planets up to Jupiter would be engulfed within the star and be instantly vaporized.
Finally, the award for the smallest known star in the universe goes to EBLM J0555-57Ab, according to a 2017 study published in the journal Astronomy and Astrophysics. The star is smaller than Saturn and barely qualifies as a star. However, it is believed that it will not be able to sustain its nuclear fusion for long and will turn into a brown dwarf.
How many galaxies are there?
What is the largest galaxy in the Universe? – The largest galaxy in the Universe is likely the ESO 383-76 supergiant elliptical galaxy, It measures 1,764,000 light-years in diameter and is found in the Centaurus Constellation, some 654 million light-years from Earth.
It is difficult to know what is the largest galaxy in the Universe, however, as we’re constantly learning more about space every day thanks to new technologies including the telescope. As such, many different galaxies have been claimed to be the largest in the Universe, including the IC 1101 and Alcyoneus galaxies.
The largest known spiral galaxy is the UGC 2885, meanwhile. When you get to the largest barred spiral galaxy in the Universe, you find the NGC 6872 (the Condor Galaxy). It’s 522,000 light-years across from one point to another, which makes it over five times the size of the Milky Way.
Does the Sun stay in one spot?
Answer: – Yes, the Sun – in fact, our whole solar system – orbits around the center of the Milky Way Galaxy. We are moving at an average velocity of 828,000 km/hr. But even at that high rate, it still takes us about 230 million years to make one complete orbit around the Milky Way! The Milky Way is a spiral galaxy.
We believe that it consists of a central bulge, 4 major arms, and several shorter arm segments. The Sun (and, of course, the rest of our solar system) is located near the Orion arm, between two major arms (Perseus and Sagittarius). The diameter of the Milky Way is about 100,000 light-years and the Sun is located about 28,000 light-years from the Galactic Center.
You can see a drawing of the Milky Way below which shows what our Galaxy would look like “face-on” and the direction in which it would spin as viewed from that vantage point. Also shown, is the location of the Sun in the big picture view of our Galaxy. It is interesting to note that recent observations by astronomers suggest that the Milky Way is in fact a “barred spiral galaxy”, not just a “spiral galaxy”. This means that rather than a simple spherical bulge of gas and stars at its center, it has instead a “bar of stars” crossing the central bulge.

Is the Sun getting bigger?
How long will the Sun shine? – If our Sun is four and a half billion years old, how much longer will it shine? Stars like our Sun burn for about nine or 10 billion years. So our Sun is about halfway through its life. But don’t worry. It still has about 5,000,000,000—five billion—years to go. article last updated May 25, 2021
What is the hottest star?
The hottest: WR 102 – WHILE STARS MAY not follow the exact ratio set by this quote from the 6th-century-b.c. Chinese work Tao Te Ching, the gist holds true. The faster a star burns through its fuel, the shorter its life. And this is surely the case for Wolf-Rayet stars.
- These stars not only burn incredibly hot and bright, but their stellar winds also blast much of their potential fuel into space.
- The hottest known star, WR 102, is one such Wolf-Rayet, sporting a surface temperature more than 35 times hotter than the Sun.
- Like Baskin-Robbins, Wolf-Rayet stars come in a variety of flavors.
The most massive star, RMC 136a1, has a spectral type of WN, meaning it’s rich in ionized nitrogen as a result of rapidly converting hydrogen to helium in its fiery core via the C-N-O cycle. However, the hottest star, WR 102, is an especially rare WO-type Wolf-Rayet, which is a late-stage star that has a surface heavily enriched with ionized oxygen.
- All said, astronomers only know of about 10 WO-type Wolf-Rayet stars in the entire universe.
- Even for a Wolf-Rayet star, WR 102 has intense stellar winds.
- Currently, they are blowing about a Sun’s worth of mass from the star’s surface every 100,000 years.
- That means WR 102 is losing several hundred million times more mass each year than the Sun.
Although that may not seem like much for a massive star, keep in mind that at this rate, WR 102 would be completely gone in less than 2 million years. But who can wait that long? Astronomers are interested in WR 102 not just because of its exceptionally hellish surface temperature and rapid mass loss, but also because the star is a prime candidate to go supernova in the relatively near future.
What is the biggest thing in the universe?
The absolute largest thing in the universe is the Hercules-Corona Borealis Great Wall, which is about 10 billion light-years across. As far as we know, the absolute largest thing in the universe is the Hercules-Corona Borealis Great Wall.
Is the Moon 1 400th the size of the Sun?

- This doesn’t always happen, partial solar eclipses merely trim away a chunk of the solar disk, and true total eclipses perfectly blank out the visible surface of the Sun.
- It’s all a matter of alignment between Sun-Moon-Earth and our mutual orbital gymnastics.
- It is an interesting coincidence that the Moon should so nearly perfectly blot out the Sun, since there is really no physical reason why this has be the case.
The Moon happens to be about 400 times smaller than the Sun, but the Sun happens to be about 400 times further from the Earth than the Moon is. So simple geometry tells us that the apparent disk of the Moon is almost exactly the size of the apparent disk of the Sun.
- Of course this match is not always quite the same, the Earth orbits the Sun in a modestly non-circular, elliptical, path and so our nearest and furthest distances (perihelion and aphelion) differ by about 3.3%.
- And the Moon’s orbit has a roughly 10% difference between its near and far point to us, so the precise degree of total solar eclipse will vary a little as the apparent sizes of Sun and Moon vary.
This Sunday the distance variations conspire to make the Moon appear 94.4% the size of the Sun. However, on longer timescales the Earth-Moon system is not static. Tidally driven evolution of the orbits and spins of these two bodies results in a number of things.
- First, as we know well, the Moon’s spin rate is matched to its orbital period so that it always has the same face to the Earth (except for some small librational wobbles ).
- Second, because the Earth’s spin is faster than the Moon’s orbit, the tidal bulge raised on the Earth pulls on the lagging moon, gradually raising its orbit and slowing our day.
Every year the Moon’s orbit grows by some 3.8 centimeters and our day lengthens by about 0.000015 seconds. At this present rate, in about 50 million years the Moon will never completely eclipse the Sun, it will simply appear too small on the sky. This orbital evolution also implies that total solar eclipses in the distant past would have been just that – completely obliterating the Sun from view. The eclipse path, from one side of the planet to the other (Credit: NASA) The views expressed are those of the author(s) and are not necessarily those of Scientific American.
Is the Moon 40 times smaller than the Sun?
Total solar eclipses won’t be around forever! – The Moon’s orbit is changing. In fact, the Moon’s orbit grows about 1.5 inches (3.8 cm) larger every year. As the Moon’s orbit takes it farther and farther away from Earth, the Moon will appear smaller and smaller in our sky.
- This occasionally happens now.
- The Moon’s orbit isn’t perfectly round.
- That means that sometimes the Moon is slightly farther away from Earth than it is at other times.
- Sometimes the Moon is far enough away that it doesn’t create a total solar eclipse.
- In this case, the Moon obscures most of the Sun, but a thin ring of the Sun remains visible around the Moon.
However, once the Moon’s growing orbit takes it approximately 14,600 miles (23,500 km) farther away from Earth, it will always be too far away to completely cover the Sun. That won’t happen for a long time though. If the Moon’s orbit grows only 1.5 inches every year, it will take more than 600 million years for total solar eclipses to completely disappear!
Do 108 moons fit between the Earth and the Moon?
SUN, MOON & EARTH RELATIONSHIP The diameter of the Moon: 2160 miles. The distance between moon and earth: 2160 x 108 = 233,000 miles. This is equal to 108 Moon.
Is the Sun 400 times the size of the Moon?
The comparative size of various solar system objects The sun and the moon are about the same size when you look at them in the sky, though that’s just thanks to the coincidence that the sun is about 400 times farther away than the moon and also about 400 times bigger.
- Another fun coincidence is that the radius of the sun is about twice the distance to the moon.
- So if you put the sun where the Earth is, the moon would be just over halfway to the surface of the sun.
- The sun is also so big that it takes light over four and 1/2 seconds to travel across its face, though I don’t know whether that says more about how big the sun is or how slow light is or both.
But what about the scale of other solar system objects? Well, here are Pluto and Charon compared to the Earth and the moon and Jupiter, which, as a rough rule of thumb, has about 10 times the radius of the Earth and one tenth the radius of the sun. Saturn is slightly smaller than Jupiter, though its rings go out twice as far.
Still only a third of the way to the moon, though. Mars’ moons are very close and very small, which gives rise to another moon-sized coincidence. Phobos is almost the same size in the Martian sky as the sun and can cause annular eclipses, just like our moon here on Earth. If two objects have the same apparent size in the sky, like the moon and the sun, it means that their radii divided by their distances have about the same value.
This also implies that the strengths of the objects’ tidal forces, which are roughly proportional to the radius over the distance cubed, will also be about the same. In fact, any two objects of roughly the same density and which look about the same size in the sky will have tidal forces of similar strengths.
