Our sunlight is the biggest celestial object in the Solar System, comprise 99.8% of all the Solar System’s mass. Contrasted to Earth, which has a massive of about 5.9 quadrillion kg, the sun is 330.000 times much more massive 보다 our tiny home planet.

You are watching: How many earths could fit in saturn

Jupiter, the largest planet in ours Solar System, has 318 earth masses, when Mercury, the smallest planet, has actually only 0.055 earth Masses. V that gift said, how countless Earths can fit inside the Sun?

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

Earth, for comparison, has actually a radius of only 2.439 km / 1.516 mi, and also a diameter of just 12.742 kilometres / 7.917 mi. Every the planets in ours Solar System combined account for just 0.2% of the Sun’s mass. However, just how do 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 kilometres / 3.032 mi, and also a radius that 2.439 km / 1.516 mi, and also only 0.055 earth masses.

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


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

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

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


Jupiter might seem superior in these regards, but it would just take approximately 1.000 Jupiter-sized planets to to fill the Sun. When it pertains to Saturn, i m sorry is the second-largest world in our Solar System, things start to change.

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

Uranus and also Neptune

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

Uranus is sensibly massive, v its mass being equivalent to 14.54 planet masses. It would take around 22.000 Uranus-sized planets to to fill the Sun. Points differ a little when it comes to Neptune. 


Neptune is the fourth-largest earth in the Solar System, having actually a diameter that 49.244 kilometres / 30.598 mi, and also a radius the 24.764 kilometres / 15.387 mi. The massive of Neptun is identical to 17.15 earth masses. You can fit around much more than 1,800 Neptune-sized planets within the Sun.


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

Pluto has a diameter of around 2.376 km / 1.476 mi and also a radius of about 1,188 km / 738 mi. It’s not rather a massive planet, because it has actually only 0.01 earth masses or simply 1% of our earth mass. Thus, it would take much more than 200 million Pluto-sized planets to to fill the Sun.


But if we space going to talk small, let’s talk around our Moon. Earth’s Moon has actually a diameter of about 3.474 kilometres / 2.158 mi and a radius that 1.737 kilometres / 1.079 mi. In comparison come Earth, the Moon has 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 come fit within the Sun, pour it until it is full it whole. If us were to fill the planet with Moons, we would need about 50 Moons to do so.

Did girlfriend know?

The largest moon in the Solar device is Ganymede, which is also the most massive moon in ours system, and the biggest moon of Jupiter.Ganymede is bigger than the dwarf world Pluto, or the world Mercury, or Mars, having actually a diameter of 5.268 km / 3.273 mi.Some theorize the if Jupiter were approximately 70 times or much more massive 보다 it currently is, it would have become a star.Sources:Image Sources:
