2003 YN107 is a very small Near-Earth object. It was discovered by the Lincoln Near Earth Asteroid Research (LINEAR) system in orbit around the Sun on December 20, 2003. Its diameter is approximately 10 to 30 metres, which is near the most commonly used 10-metre demarcation line between meteoroids and asteroids. 2003 YN107 is on NASA's Earth Close Approach list, and is estimated to miss the Earth by 0.0599 AU.

Earth Coorbital Asteroid 2003 YN107 is making a close flyby today. The asteroid's corkscrew path is lopsided and on June 10th it will dip within 3.4 million km of the Earth, slightly closer than usual. Earth's gravity will then give the asteroid the nudge it needs to leave. Using Ephemeredes predictions, on June 10th 2003 YN107 has 28mag. and elong. 23 deg. It won't be gone forever. In about 60 years 2003 YN107 will lap Earth again, resuming its role as a temporary, corkscrewing moonlet. In due course, other coorbitals will do the same. Read more
