How many Earths would fit inside the Sun?
The Sun holds more than 99% of all the mass in the solar system. If it were hollow and you poured in planets the size of ours, how many would it take to fill it?
Reveal the answer
About 1.3 million by volume. The Sun is much less dense than our planet, though, so it would take only about 330,000 Earths to match its mass.
