Our sunlight is the biggest celestial object in the Solar System, include 99.8% of all the Solar System’s mass. Contrasted to Earth, which has a fixed of approximately 5.9 quadrillion kg, the sun is 330.000 times an ext massive than our little home planet.

You are watching: How many moons can fit in the earth

Jupiter, the largest planet in our Solar System, has actually 318 earth masses, when Mercury, the the smallest planet, has actually only 0.055 planet Masses. With that being said, how plenty of Earths deserve to fit within the Sun?

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

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

Mercury, Venus, and Mars

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

It would certainly take around much more than 21.2 million Mercury-sized planets to fit within the Sun. Once it comes to Venus, things gain a little bit different. Venus is the sixth-largest earth from the Sun, having actually a diameter of 12.104 km / 7.521 mi, and a radius of about 6.051 kilometres / 3.760 mi. The mass of Venus is equivalent to 0.9 planet masses, or 90% the our earth’s mass.


When compare Venus come the Sun, it starts to shrink drastically, together you might fit 1.5 million Venus-sized planets inside the Sun, if it were hallowed.

Now let’s talk about Mars. Mars is the second-smallest world in the Solar System, having actually a diameter of just 6.779 km / 4.212 mi (30% bigger than Mercury), and also a radius the 3.389 km / 2.105 mi. Mars has actually only 11% that our earth 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 good gas giants, Jupiter and Saturn, the numbers start to go down or increase in other cases. Jupiter is the biggest planet in our Solar System yet pales when compared in dimension to the Sun and also any other aspects.

Jupiter has a diameter of around 142.984 kilometres / 88.846 mi in ~ the equator, and a diameter of about 133.708 kilometres / 83.082 mi at the poles. It has actually a median radius that 69.911 kilometres / 43.440 mi, and also its mass is equivalent to 318 earth masses. You can fit 1.300 Earths within Jupiter.


Jupiter can seem impressive in these regards, yet it would only take roughly 1.000 Jupiter-sized planets to fill the Sun. When it comes to Saturn, i beg your pardon is the second-largest planet in our Solar System, things start to change.

Saturn has actually a diameter of roughly 120.536 km / 74.897 mi and a radius of roughly 58.232 km / 36.183 mi. That is quite massive as well, having the identical of 95.16 planet masses. It would take an ext than 1,700 Saturn-sized planets to fill the Sun.

Uranus and also Neptune

The icy giants, Uranus and also Neptune, room a bit comparable in size and mass yet lets how they fare against the Sun. Let’s start with Uranus, i beg your pardon is the third-largest planet in the Solar System. Uranus has actually a diameter of around 51.118 km / 31.763 mi and also a radius that 25.362 km / 15.759 mi.

Uranus is fairly massive, v its massive being identical to 14.54 planet masses. It would take about 22.000 Uranus-sized planets to to fill the Sun. Things differ a bit when it pertains to Neptune. 


Neptune is the fourth-largest earth in the Solar System, having a diameter that 49.244 km / 30.598 mi, and a radius of 24.764 km / 15.387 mi. The massive of Neptun is tantamount to 17.15 earth masses. You have the right to fit around an ext than 1,800 Neptune-sized planets inside the Sun.


Let’s talk about a planet that no longer fits in, yes, the dwarf world Pluto. Pluto is the ninth-largest planet in the Solar System, and though numerous don’t regard it as a earth anymore, we figured that deserves a spot below regardless.

Pluto has a diameter of about 2.376 km / 1.476 mi and also a radius of around 1,188 km / 738 mi. It’s not fairly a huge planet, due to the fact that it has actually only 0.01 planet masses or just 1% the our earth’s mass. Thus, it would certainly take an ext than 200 million Pluto-sized planets to fill the Sun.


But if we are going to speak small, let’s talk around our Moon. Earth’s Moon has a diameter of around 3.474 kilometres / 2.158 mi and also a radius that 1.737 km / 1.079 mi. In comparison to Earth, the Moon has actually only 1.2% of earth mass, or in another means of looking in ~ it, the earth is 81 time heavier 보다 the Moon.

It would take about 64.3 million Moons to fit within the Sun, filling it whole. If we were to fill the planet with Moons, we would certainly need around 50 Moons to do so.

Did you know?

The largest moon in the Solar device is Ganymede, which is also the most huge moon in our system, and the greatest moon the Jupiter.Ganymede is larger than the dwarf world Pluto, or the world Mercury, or Mars, having actually a diameter the 5.268 kilometres / 3.273 mi.Some theorize that if Jupiter were about 70 time or more massive 보다 it right now is, it would certainly have become a star.Sources:Image Sources:
