Our Sun is the biggest celestial object in the Solar System, containing 99.8% of all the Solar System’s mass. Compared to Planet, which has a mass of about 5.9 quadrillion kg, the Sun is 330.000 times more huge than our bit house earth.

You are watching: How many moons would fit in the sun

Jupiter, the largest earth in our Solar System, has actually 318 Earth masses, while Mercury, the smallest world, has actually only 0.055 Earth Masses. With that being sassist, just how many Earths can fit inside the Sun?

More than one million Earths could fit inside the Sun if it were hollow. The Sun has a radius of 696.340 kilometres / 432.685 mi and a diameter of 1.39 million km / 864.000 mi.

Earth, for comparison, has a radius of just 2.439 kilometres / 1.516 mi, and also a diameter of simply 12.742 kilometres / 7.917 mi. All the planets in our Solar System unified account for just 0.2% of the Sun’s mass. However, how perform the various other planets fare in these comparisons? Let’s find out!

Mercury, Venus, and Mars

Mercury is the smallest world in our Solar System, having a diameter of only 4.879 km / 3.032 mi, and a radius of 2.439 kilometres / 1.516 mi, and also just 0.055 Planet masses.

It would certainly take roughly more than 21.2 million Mercury-sized planets to fit inside the Sun. When it concerns Venus, things gain a little various. Venus is the sixth-biggest planet from the Sun, having a diameter of 12.104 km / 7.521 mi, and a radius of around 6.051 km / 3.760 mi. The mass of Venus is identical to 0.9 Planet masses, or 90% of our Earth’s mass.


When comparing Venus to the Sun, it starts to shrink considerably, as you could fit 1.5 million Venus-sized planets inside the Sun, if it were henabled.

Now let’s talk about Mars. Mars is the second-smallest world in the Solar System, having a diameter of just 6.779 km / 4.212 mi (30% bigger than Mercury), and a radius of 3.389 km / 2.105 mi. Mars has only 11% of our Earth’s mass or 0.11 Planet masses. It would take around 7 million Mars-sized planets to fill the Sun.

Jupiter and also Saturn

Moving on to the excellent gas giants, Jupiter and Saturn, the numbers start to go dvery own or up in various other situations. Jupiter is the biggest world in our Solar System however pales as soon as compared in dimension to the Sun and also any type of other facets.

Jupiter has actually a diameter of about 142.984 km / 88.846 mi at the equator, and also a diameter of around 133.708 km / 83.082 mi at the poles. It has actually a expect radius of 69.911 km / 43.440 mi, and also its mass is equivalent to 318 Earth masses. You could fit 1.300 Earths inside Jupiter.


Jupiter might seem exceptional in these regards, yet it would certainly just take approximately 1.000 Jupiter-sized planets to fill the Sun. When it pertains to Sarevolve, which is the second-largest world in our Solar System, things start to readjust.

Saturn has actually a diameter of about 120.536 kilometres / 74.897 mi and a radius of approximately 58.232 km / 36.183 mi. It is fairly huge as well, having the indistinguishable of 95.16 Earth masses. It would certainly take even more than 1,700 Saturn-sized planets to fill the Sun.

Uranus and Neptune

The icy giants, Uranus and Neptune, are a little bit comparable in size and also mass however lets how they fare versus the Sun. Let’s start through Uranus, which is the third-biggest planet in the Solar System. Uranus has a diameter of around 51.118 km / 31.763 mi and also a radius of 25.362 kilometres / 15.759 mi.

Uranus is reasonably huge, via its mass being indistinguishable to 14.54 Planet masses. It would take approximately 22.000 Uranus-sized planets to fill the Sun. Things differ a little bit once it comes to Neptune. 


Neptune is the fourth-largest earth in the Solar System, having a diameter of 49.244 kilometres / 30.598 mi, and also a radius of 24.764 kilometres / 15.387 mi. The mass of Neptun is equivalent to 17.15 Earth masses. You have the right to fit about more than 1,800 Neptune-sized planets inside the Sun.


Let’s talk around a world that no much longer fits in, yes, the dwarf planet Pluto. Pluto is the ninth-biggest planet in the Solar System, and though many kind of don’t regard it as a planet anymore, we figured it deserves a spot right here regardless.

Pluto has actually a diameter of around 2.376 kilometres / 1.476 mi and also a radius of around 1,188 kilometres / 738 mi. It’s not rather a huge earth, considering that it has actually only 0.01 Planet masses or simply 1% of our Earth’s mass. Therefore, it would take more than 200 million Pluto-sized planets to fill the Sun.


But if we are going to talk tiny, let’s talk about our Moon. Earth’s Moon has actually a diameter of about 3.474 kilometres / 2.158 mi and also a radius of 1.737 kilometres / 1.079 mi. In compariboy to Earth, the Moon has only 1.2% of Earth’s mass, or in another method of looking at it, the Earth is 81 times heavier than the Moon.

It would take approximately 64.3 million Moons to fit inside the Sun, filling it whole. If we were to fill the Earth with Moons, we would certainly need approximately 50 Moons to carry out so.

Did you know?

The biggest moon in the Solar System is Ganymede, which is additionally the a lot of substantial moon in our device, and also the best moon of Jupiter.Ganymede is bigger than the dwarf world Pluto, or the planet Mercury, or Mars, having actually a diameter of 5.268 kilometres / 3.273 mi.Some theorize that if Jupiter were roughly 70 times or more huge than it presently is, it would certainly have actually come to be a star.Sources:Image Sources:
