Orbit With an orbital period of 364.3 days, 1998 UP 1 is in a near 1:1 orbital resonance with Earth. Although their periods are almost identical, their orbits are very different; 1998 UP 1 has a highly eccentric orbit and moves between 0.65–1.35 AU from the Sun, it is also very highly inclined at 33°. The preliminary period of 1998 UP 1 was originally thought to be slightly longer than 1 year producing an error in the predicted position of about 35 degrees; it was selected as a priority for recovery and recovered by the Camarillo Observatory on 12 October 1999.Coordinated Amateur Recovery of One-Opposition NEAs Rogers John E.
