2012 UE34 is a small asteroid that is a Near-Earth object and an Apollo asteroid. It was removed from the Sentry Risk Table on December 29, 2013.[4]
Orbit
Because of the orbit of 2012 UE34, the asteroid will pass within 0.00092 AU (138,000 km; 86,000 mi) from Earth on April 8, 2041.[5] For comparison, the distance to the Moon is about 0.0026 AU (384,400 km). The asteroid is not listed as a Potentially Hazardous Asteroid (PHA), and does not appear on the list of PHA close approaches issued by the Minor Planet Center (MPC) because the absolute magnitude (H) of 23 is too dim.[6] The asteroid passed within 0.00267 AU (399,000 km; 248,000 mi) from Earth on April 8, 1991.[5]
2012 UE34 has a very small Earth Minimum Orbit Intersection Distance (MOID) of 0.000036 AU (5,400 km; 3,300 mi). The Jupiter Tisserand invariant is 5.6 ruling out any realistic probability that the object is cometary.[2]
