Our Sun is the greatest celestial object in the Solar System, containing 99.8% of all the Solar System’s mass. Contrasted to Planet, which has a mass of about 5.9 quadrillion kg, the Sun is 330.000 times even more massive than our little bit residence world.

You are watching: How many earths could fit in saturn

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

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

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

Mercury, Venus, and Mars

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

It would take about even more than 21.2 million Mercury-sized planets to fit inside the Sun. When it concerns Venus, things get a little different. Venus is the sixth-biggest earth from the Sun, having a diameter of 12.104 kilometres / 7.521 mi, and also a radius of roughly 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 drastically, as you can 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 earth in the Solar System, having actually a diameter of just 6.779 km / 4.212 mi (30% bigger than Mercury), and also a radius of 3.389 km / 2.105 mi. Mars has only 11% of our Earth’s mass or 0.11 Earth masses. It would take about 7 million Mars-sized planets to fill the Sun.

Jupiter and Saturn

Moving on to the great gas giants, Jupiter and also Sarevolve, the numbers start to go dvery own or up in other cases. Jupiter is the biggest earth in our Solar System yet pales once compared in dimension to the Sun and any type of various other aspects.

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


Jupiter could seem exceptional in these regards, but it would only take around 1.000 Jupiter-sized planets to fill the Sun. When it comes to Saturn, which is the second-largest planet in our Solar System, points start to adjust.

Sarevolve has a diameter of about 120.536 km / 74.897 mi and also a radius of approximately 58.232 kilometres / 36.183 mi. It is quite huge too, having actually the tantamount of 95.16 Planet masses. It would take even more than 1,700 Saturn-sized planets to fill the Sun.

Uranus and Neptune

The icy giants, Uranus and also Neptune, are a bit equivalent in size and also mass yet allows how they fare against the Sun. Let’s start via Uranus, which is the third-largest planet in the Solar System. Uranus has a diameter of about 51.118 km / 31.763 mi and also a radius of 25.362 kilometres / 15.759 mi.

Uranus is sensibly substantial, through its mass being identical to 14.54 Planet masses. It would take about 22.000 Uranus-sized planets to fill the Sun. Things differ a little bit as soon as it pertains to Neptune. 


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


Let’s talk around a planet that no longer fits in, yes, the dwarf planet Pluto. Pluto is the ninth-largest earth in the Solar System, and also though many kind of don’t regard it as a planet anymore, we figured it deserves a spot below regardmuch less.

Pluto has a diameter of approximately 2.376 km / 1.476 mi and a radius of roughly 1,188 km / 738 mi. It’s not quite a enormous earth, considering that it has only 0.01 Earth masses or just 1% of our Earth’s mass. Therefore, it would certainly take even more than 200 million Pluto-sized planets to fill the Sun.


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

It would take about 64.3 million Moons to fit inside the Sun, filling it entirety. If we were to fill the Earth through Moons, we would need approximately 50 Moons to execute so.

Did you know?

The biggest moon in the Solar System is Ganymede, which is likewise the many substantial moon in our mechanism, and the greatest moon of Jupiter.Ganymede is larger than the dwarf world Pluto, or the world Mercury, or Mars, having actually a diameter of 5.268 km / 3.273 mi.Some theorize that if Jupiter were around 70 times or even more substantial than it presently is, it would certainly have come to be a star.Sources:Image Sources:
