So, how many Earths can fit in the Sun? The answer is that it would take 1.3 million Earth to fill up the Sun. That's a lot of Earths.

The Sun makes up 99.86% of the mass of the Solar System. And it's the giant planets like Jupiter and Saturn which make the most of that remaining .14% of the Solar System.

If you'd like to do the calculation yourself, here are your numbers. The volume of the Sun is 1.412 x 10^18 km3. And the volume of the Earth is 1.083 x 10^12 km3. So if you divide the volume of the Sun by the volume of the Earth, you get 1,300,000.

Of course, the Sun is a fairly average-sized star. There are some enormous stars out there. For example, the red giant Betelgeuse has a radius of 936 times the radius of the Sun. That gives it hundreds of millions of times more volume than the Sun.
