Oseidon

Oseidon was a barren, desert-covered planet located in Mutter's Spiral. Though similar to Earth in terms of gravity and atmosphere, it had some of the highest levels of radiation in the galaxy. This radiation became increasingly more powerful as time went on, forcing the native Kraals to search for a new home. The planet Oseidon was later turned into a duplicate Earth by the Kraals as part of their invasion plans. (TV: The Android Invasion)
