(524522) 2002 VE68
(524522) 2002 VE68 is an asteroid and a temporary quasi-satellite of Venus.[1] It was the first quasi-satellite to be found around a planet in the Solar System. It looks like it travels around Venus during one Venerean year but it actually orbits the Sun, not Venus.[2]
Discovery, orbit and physical properties
changeIt was discovered on 11 November 2002 at Lowell Observatory. It has a semi-major axis of 0.7237 AU. Its eccentricity is 0.4104. Its orbital inclination is 9.0060°. It is calculated to measure 236 meters in diameters. Its rotational period is 13.5 hours.[3]
Potentially hazardous asteroid
change2002 VE68 is in the Minor Planet Center list of Potentially Hazardous Asteroids (PHAs) because it frequently comes as close as 0.05 AU (7,479,894 km) to Earth. It comes as close as 0.04 AU (5,983,915 km) every 8 years.[4]
