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. It orbits the sun just under 248 Earth years. Chadwick A. Trujillo (born November 22, 1973) is a postdoctoral scholar at Caltech researching the Edgeworth-Kuiper belt and the outer solar system. ...
