Detection, orbit and physical characteristics
2012 XE 133 was first observed on December 12, 2012 by J. A. Johnson as part of the Catalina Sky Survey review. As of March 2013, the asteroid was observed 102 times, the observation arc was 28 days. The semimajor axis of the asteroidβs orbit is 0.72 AU, the semimajor axis of Venusβs orbit is approximately the same. The eccentricity of the orbit is 0.4332, the inclination of the orbit is 6.7 Β°. The absolute magnitude is 23.4, and the diameter estimate is 62β138 meters.
The dynamic state of a quasi-satellite and the evolution of the orbit
2012 XE 133 is considered the co-orbiting satellite of Venus, located on the transition path between the Lagrange points L5 and L3 for Venus. [4] In addition to its arrangement in the co-orbital configuration with Venus, the asteroid crosses the orbits of Mercury and the Earth. 2012 XE 133 is near resonance with Mercury, Venus and the Earth. [4] Dynamic evolution at small time scales is similar to the evolution of other co-orbiting satellites of Venus, 2001 CK 32 and 2002 VE 68 . [four]
Potentially Dangerous Asteroids
2012 XE 133 was included in the list of potentially dangerous asteroids by the Center for Small Planets , because the asteroid periodically approaches the Earth at a distance of less than 0.05 AU, but was then removed from the list. December 30, 2028 the asteroid will approach the Earth at a distance of 0.0055 AU
