Coreilla is the home planet of the Rebellion hero and smuggler, Han Solo. In the seven live action films that have so far been produced, Corellia has not appeared in any of them. The planet is said to be similiar in looks to Earth, different temperatures and environments.
The only information about Coreilla comes from the expanded stories from the books but hopefully that might change. In the expanded stories it gives a world with snow covered hills and one with a variety of environments such as you see in Naboo.
