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

You are watching: How many uranus can fit in the sun

Jupiter, the largest planet in our Solar System, has actually 318 earth masses, when Mercury, the the smallest planet, has actually only 0.055 earth Masses. Through that being said, how numerous Earths can fit inside the Sun?

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

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

Mercury, Venus, and Mars

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

It would certainly take around more than 21.2 million Mercury-sized planets to fit inside the Sun. As soon as it concerns Venus, things obtain a bit different. Venus is the sixth-largest earth from the Sun, having actually a diameter of 12.104 km / 7.521 mi, and also a radius of around 6.051 kilometres / 3.760 mi. The massive of Venus is indistinguishable to 0.9 earth masses, or 90% that our earth mass.


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

Now let’s talk around Mars. Mars is the second-smallest world in the Solar System, having actually a diameter of only 6.779 km / 4.212 mi (30% bigger 보다 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 about 7 million Mars-sized planets to to fill the Sun.

Jupiter and also Saturn

Moving on come the an excellent gas giants, Jupiter and Saturn, the numbers start to go down or up in various other cases. Jupiter is the best planet in our Solar System but pales when compared in dimension to the Sun and any other aspects.

Jupiter has a diameter of approximately 142.984 kilometres / 88.846 mi in ~ the equator, and a diameter of around 133.708 kilometres / 83.082 mi at the poles. It has a mean radius the 69.911 km / 43.440 mi, and its fixed is equivalent to 318 earth masses. You might fit 1.300 Earths inside Jupiter.


Jupiter can seem impressive in these regards, however it would only take roughly 1.000 Jupiter-sized planets to fill the Sun. Once it pertains to Saturn, which is the second-largest earth in our Solar System, things begin to change.

Saturn has a diameter of roughly 120.536 kilometres / 74.897 mi and a radius of around 58.232 kilometres / 36.183 mi. The is quite massive as well, having the indistinguishable of 95.16 earth masses. It would take more than 1,700 Saturn-sized planets to fill the Sun.

Uranus and also Neptune

The icy giants, Uranus and Neptune, space a bit similar in size and also mass but lets exactly how they fare against the Sun. Let’s begin with Uranus, i beg your pardon is the third-largest earth in the Solar System. Uranus has actually a diameter of roughly 51.118 km / 31.763 mi and also a radius of 25.362 km / 15.759 mi.

Uranus is reasonably massive, through its mass being indistinguishable to 14.54 planet masses. It would take roughly 22.000 Uranus-sized planets to fill the Sun. Things differ a little bit when it pertains to Neptune. 


Neptune is the fourth-largest planet in the Solar System, having a diameter that 49.244 kilometres / 30.598 mi, and a radius that 24.764 km / 15.387 mi. The fixed of Neptun is tantamount to 17.15 planet masses. You deserve to fit around much more than 1,800 Neptune-sized planets inside the Sun.


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

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


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

It would certainly take roughly 64.3 million Moons to fit within the Sun, pour it until it is full it whole. If us were to fill the planet with Moons, we would certainly need approximately 50 Moons to carry out so.

Did girlfriend know?

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