Hail, Jupiter!

Astronomy by Sanoik:

Jupiter, the gaseous giant of our Solar System.
Within it would fit thousands of Earths.

Your electromagnetic field is the greatest thing that exists in the Solar System. Were it not for the existence of this giant, we would be hit all the time by comets and asteroids, which would make life on Earth impossible.

And if it were a little larger, its structure would have collapsed nuclearly like the gases and dust that formed the Sun and it would be the second star of the Solar System and we would have two suns.

Hail, Jupiter!
