Many Classifications
Once upon a time, Ceres was considered an asteroid, or a minor planet for a brief period of time. It was once the "eighth planet" in the Solar System, rather than Neptune because Neptune yet wasn't discovered. It is today known as a dwarf planet.

White Spots
The Dawn spacecraft saw white areas on Ceres. Today they are possibly ice or salt. The brightest cluster of spots ("Spot 5") is located in an 80-kilometer (50 mi) crater called Occator.
