2003 AZ84, also written as 2003 AZ84, is a Trans-Neptunian object. It was discovered on January 13, 2003 by C. Trujillo, M. Brown, E. Helin, S. Pravdo, K. Lawrence, and M. Hicks at the Palomar Observatory using the Schmidt telescope. It is classified as a plutino, which means that it is in a 3:2 orbital resonance with Neptune, similar to that of Pluto.
[edit] Satellite
