2003 YN107 is a tiny asteroid, classified as a near-Earth object of the Aten group moving in a 1:1 mean-motion resonance with Earth. Because of that, it is in a co-orbital configuration relative to Earth.[2][3][4]
Discovery, orbit and physical properties
[edit]2003 YN107 was discovered by the Lincoln Near Earth Asteroid Research (LINEAR) system in orbit around the Sun on 20 December 2003. Its diameter is approximately 10 to 30 metres. The object is on NASA's Earth Close Approach list, and is estimated to miss Earth by 0.01
Co-orbital with Earth and orbital evolution
[edit]From approximately 1997 to 2006, the asteroid remained within 0.1
