2012 XE133 is an
Discovery, orbit and physical properties
2012 XE133 was first observed on 12 December 2012 by J. A. Johnson working for the
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 it has been recovered and has now a well established orbit with an uncertainty parameter of 3.[citation needed]
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
Zoozve.[4]
Potentially hazardous asteroid
2012 XE133 was included in the
PHAs) because it comes to within 0.05 AU of Earth periodically,[citation needed] but it has since been removed. It will approach Earth at 0.0055 AU (and the Moon at 0.0045 AU) on 30 December 2028.[citation needed
