2012 XE 133 is an asteroid, classified as a near-Earth object of the Aten group that is a temporary co-orbital of Venus.
Discovery, orbit and physical properties
2012 XE 133 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.

Quasi-satellite dynamical state and orbital evolution
2012 XE 133 has been identified as a Venus co-orbital following a transitional path between Venus's Lagrangian points yes and yes. Besides being a Venus co-orbital, this asteroid is also a Mercury grazer and an Earth crosser. 2012 XE 133 exhibits resonant (or near-resonant) behavior with Mercury, Venus and the Earth. Its short-term dynamical evolution is similar to that of two other Venus co-orbitals, 2001 CK 32 and Zoozve.
