Earth is a planet with a moon. It is home to superheroes such as Hulk, Thor, Beta Ray Bill, Iron Man, Doctor Strange, Mister Fantastic, and Black Bolt. A group of four Kronans landed there thinking they would conquer the planet. Thor and Beta Ray Bill destroyed their Warbot and forced them to flee while Bill followed. The latter four heroes, as the Illuminati, banished Hulk to another planet, but he got lost and crashed on Sakaar. After Bill freed Hulk from gladiator games on Sakaar he returned to Earth. The Kronan Korg described it "as green as the Hulk."
