Our sunlight is the best celestial thing in the Solar System, containing 99.8% of every the Solar System’s mass. Contrasted to Earth, which has actually a massive of approximately 5.9 quadrillion kg, the sun is 330.000 times much more massive 보다 our small home planet.

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

Jupiter, the largest planet in our Solar System, has 318 earth masses, if Mercury, the smallest planet, has actually only 0.055 planet Masses. Through that gift said, how numerous Earths have the right to fit inside the Sun?

More 보다 one million Earths could fit within the sun if it were hollow. The Sun has a radius the 696.340 kilometres / 432.685 mi and also a diameter that 1.39 million km / 864.000 mi.

Earth, because that comparison, 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 ours Solar System combined account for simply 0.2% the the Sun’s mass. However, exactly how do the other planets fare in this comparisons? Let’s uncover out!

Mercury, Venus, and also Mars

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

It would take around more than 21.2 million Mercury-sized planets come fit inside the Sun. When it involves Venus, things obtain a little different. Venus is the sixth-largest earth from the Sun, having actually a diameter of 12.104 kilometres / 7.521 mi, and also a radius of around 6.051 km / 3.760 mi. The mass of Venus is indistinguishable 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 could 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 a diameter of just 6.779 kilometres / 4.212 mi (30% bigger than Mercury), and also a radius the 3.389 kilometres / 2.105 mi. Mars has only 11% of our earth’s mass or 0.11 earth masses. It would take around 7 million Mars-sized planets to to fill the Sun.

Jupiter and Saturn

Moving on to the great gas giants, Jupiter and Saturn, the numbers begin to go down or up in various other cases. Jupiter is the best planet in our Solar System however pales when contrasted in size to the Sun and any 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 in ~ the poles. It has a mean radius the 69.911 kilometres / 43.440 mi, and also its massive is indistinguishable to 318 earth masses. You can fit 1.300 Earths inside Jupiter.


Jupiter could seem impressive in this regards, yet it would only take approximately 1.000 Jupiter-sized planets to fill the Sun. Once it concerns Saturn, which is the second-largest planet in our Solar System, things start to change.

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

Uranus and Neptune

The icy giants, Uranus and also Neptune, space a bit similar in size and also mass but lets just how they fare against the Sun. Let’s begin with Uranus, which is the third-largest earth in the Solar System. Uranus has a diameter of about 51.118 kilometres / 31.763 mi and also a radius of 25.362 kilometres / 15.759 mi.

Uranus is fairly massive, through its fixed being equivalent to 14.54 planet masses. It would certainly take approximately 22.000 Uranus-sized planets to to fill the Sun. Things differ a little bit when it involves Neptune. 


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


Let’s talk about a planet that no much longer fits in, yes, the dwarf earth Pluto. Pluto is the ninth-largest planet in the Solar System, and though plenty of don’t to the it as a world anymore, us figured that deserves a spot right here regardless.

Pluto has actually a diameter of roughly 2.376 kilometres / 1.476 mi and also a radius of about 1,188 kilometres / 738 mi. It’s not quite a huge planet, since it has actually only 0.01 planet masses or just 1% of our earth’s mass. Thus, it would take more than 200 million Pluto-sized planets to fill the Sun.


But if we room going to speak small, let’s talk about our Moon. Earth Moon has actually a diameter of about 3.474 km / 2.158 mi and also a radius of 1.737 kilometres / 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 times heavier 보다 the Moon.

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

Did girlfriend know?

The biggest moon in the Solar system is Ganymede, i beg your pardon is also the most huge moon in our system, and also the best moon the Jupiter.Ganymede is bigger than the dwarf earth Pluto, or the planet Mercury, or Mars, having actually a diameter the 5.268 km / 3.273 mi.Some theorize that if Jupiter were roughly 70 times or more massive 보다 it right now is, it would certainly have become a star.Sources:Image Sources:
