How Big Is the Planet Jupiter and How Big Does Jupiter Have To Be To Become a Star Like the Sun?

If Jupiter had just eighty times more mass, it could be a star.

However, if it were a star, Earth would not exist.

Jupiter and the Sun would be a binary star system and the solar system would be completely different.

The largest planet in the solar system, Jupiter measures near 88,700 miles (141,920 km) around its equator.

The diameter measured from pole to pole, however, is almost 6,000 miles (9,600 km) shorter.

This difference in diameter results from Jupiter’s fast rotation speed, which causes the equator to bulge, and the poles to flatten out.
