# How Many Earths Can Fit Inside the Sun?

The Sun is the largest object in our solar system. The Sun’s volume would need 1.3 million Earths to fill it.

The sun is a star at the center of the solar system, a sphere made up of hot plasma and magnetic fields. Its diameter is about 1,392,000 km (864,000 miles), nearly 109 times larger than the Earth, and its mass is 330,000 times that of the Earth. In fact, by mass, the sun makes up over 99.86% of the solar system, whereas gas giants like Jupiter and Saturn comprise most of the remaining 0.14%.

In order to comprehend the sheer scale of the sun, it’s worth asking the question: how many Earth-sized planets can you fit inside the sun?

In terms of volume, almost 1.3 million earths could fit into the sun (1,412 x 1018 km3). That assumes all these millions of earths are squeezed together with no empty space in between. But the shape of the Earth is spherical, not a cube, so only about 960,000 Earths would fit in the Sun’s volume.

Jupiter, the largest planet in our solar system, has 318 Earth masses, while Mercury, the smallest planet, is only 0.055 Earth mass. That being said, how many earths can fit in the sun?

More than a million earths could fit in the sun if it were hollow. The Sun has a radius of 696.340 km/432.685 mi and a diameter of 1.39 million km/864.000 mi.

For comparison, the Earth has a radius of just 2.439 km/1.516 mi and a diameter of just 12.742 km/7.917 mi. All planets in our solar system together make up only 0.2% of the sun’s mass. But how do the other planets fare in these comparisons? Let’s find out!

Earth is neither the largest nor the smallest planet in the solar system. Mercury (0.055 times the volume of Earth), Venus (0.85 times the volume of Earth), and Mars (0.151 times the volume of Earth) are all smaller than Earth. It would take 17.45 million Mercury-sized planets, 1.12 million Venus-sized planets, and 6.3 million Mars-sized planets to fill the Sun, not including gaps.

On the other hand, you could fit 726 Jupiter-sized planets (1,321 Earth’s volume) and 1,256 Saturn-sized planets (764 Earth’s volume) into a hollow sun, gaps not included.
