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

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

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

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

Earth, because that comparison, has actually a radius of only 2.439 kilometres / 1.516 mi, and also a diameter of simply 12.742 km / 7.917 mi. Every the planets in ours Solar System an unified account for just 0.2% that the Sun’s mass. However, exactly how do the various other planets fare in these comparisons? Let’s find out!

Mercury, Venus, and also Mars

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

It would take around much more than 21.2 million Mercury-sized planets come fit inside the Sun. As soon as it pertains to Venus, things obtain a little different. Venus is the sixth-largest earth from the Sun, having a diameter of 12.104 kilometres / 7.521 mi, and a radius of roughly 6.051 kilometres / 3.760 mi. The fixed of Venus is identical to 0.9 planet masses, or 90% the our earth’s mass.


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

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

Jupiter and Saturn

Moving on come the good gas giants, Jupiter and also Saturn, the numbers start to go down or up in other cases. Jupiter is the biggest planet in ours Solar System however pales when contrasted in size to the Sun and also any various other aspects.

Jupiter has actually a diameter of around 142.984 km / 88.846 mi in ~ the equator, and also a diameter of about 133.708 kilometres / 83.082 mi at the poles. It has a typical radius of 69.911 km / 43.440 mi, and also its massive is identical to 318 earth masses. You might fit 1.300 Earths inside Jupiter.


Jupiter can seem outstanding in these regards, however it would just take around 1.000 Jupiter-sized planets to fill the Sun. As soon as it pertains to Saturn, which is the second-largest earth in our Solar System, things begin to change.

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

Uranus and Neptune

The icy giants, Uranus and Neptune, space a bit comparable in size and mass yet lets just how they fare versus the Sun. Let’s begin with Uranus, i m sorry is the third-largest world in the Solar System. Uranus has actually a diameter of about 51.118 kilometres / 31.763 mi and also a radius the 25.362 km / 15.759 mi.

Uranus is reasonably massive, with its mass being tantamount to 14.54 planet masses. It would certainly take around 22.000 Uranus-sized planets to fill the Sun. Things differ a bit when it concerns Neptune. 


Neptune is the fourth-largest planet in the Solar System, having actually a diameter of 49.244 kilometres / 30.598 mi, and also a radius that 24.764 km / 15.387 mi. The massive of Neptun is indistinguishable to 17.15 earth masses. You have the right to fit around much 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 earth Pluto. Pluto is the ninth-largest world in the Solar System, and though numerous don’t regard it as a planet anymore, us figured that deserves a spot here regardless.

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


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

It would certainly take about 64.3 million Moons to fit within the Sun, filling it whole. If us were to to fill the earth with Moons, we would certainly need about 50 Moons to carry out so.

Did friend know?

The biggest moon in the Solar mechanism is Ganymede, i beg your pardon is additionally the most massive moon in our system, and also the best moon of Jupiter.Ganymede is larger than the dwarf world Pluto, or the earth Mercury, or Mars, having a diameter of 5.268 kilometres / 3.273 mi.Some theorize that if Jupiter were approximately 70 time or an ext massive 보다 it right now is, it would have become a star.Sources:Image Sources:
