(524522) 2002 VE 68 is a near-Earth asteroid of the Aten type , which was discovered on November 11, 2002 by the LONEOS project of the Lowell Observatory.
The asteroid is in 1: 1 resonance to Venus and is currently its only known quasi-satellite . This is the first of its kind to be discovered and so far the only known coorbital companion of Venus. 2002 VE 68 , viewed from Venus, seems to orbit the planet once within a Venus year, but it is actually in an orbit around the sun. It is calculated that it has been in its current orbit for 7,000 years and will follow it for another 500 years. Due to the high eccentricity of about 0.4 and the inclination of around 9 °, its maximum distance from the sun is almost as great as that of the earth and its minimum distance smaller than the aphelion of Mercury ; it is also approaching the earth. The asteroid is believed to have been a near-Earth asteroid about 7,000 years ago that was brought into its current orbit by the Earth itself.
