2012 XE133 is an asteroid, classified as a near-Earth object of the Aten group that is a temporary co-orbital of Venus.[4]

Discovery, orbit and physical properties

2012 XE133 was first observed on 12 December 2012 by J. A. Johnson working for the Catalina Sky Survey. As of January 2026, it has been observed 180 times with a data-arc span of about 8 years. It is an Aten asteroid and its semi-major axis of 0.72 AU is very similar to that of Venus but its eccentricity is rather large (0.4332) and its inclination of 6.7° is also significant. With an absolute magnitude of 23.4, it has a diameter of approximately 62 to 138 meters. On 26 November 2020, 2012 XE133 was recovered[5] and now has a well established orbit with an uncertainty parameter of 0.[6][7] The asteroid often makes close approaches to Earth within 0.05 AU, and the next close approach will occur on 30 December 2028, approaching Earth at 0.0099 AU (and the Moon at 0.0080 AU).[7]

Quasi-satellite dynamical state and orbital evolution

2012 XE133 has been identified as a Venus co-orbital following a transitional path between Venus's Lagrangian points L5 point and L3 point.[4] Besides being a Venus co-orbital, this asteroid is also a Mercury grazer and an Earth crosser. 2012 XE133 exhibits resonant (or near-resonant) behavior with Mercury, Venus and the Earth.[4] Its short-term dynamical evolution is similar to that of two other Venus co-orbitals, 2001 CK32 and Zoozve.[4]
