Io - Moon of Jupiter.
Hell in the solar system
Io is full of highly active volcanism. The surface is a hellish place. It’s hot and constantly errupting. It’s believed that the moon is super hot because of the force of Jupiter’s gravity constantly pulling on it, creating heat.
The eruptions glow bright colors because it’s shooting ions into space. Now that’s cool.
