(137108) 1999 AN10 is a near-Earth asteroid (NEA) of the Apollo group. It was discovered by LINEAR on January 13, 1999.

On August 7, 2027, this NEA will pass within 0.0026 AU (390,000 km; 240,000 mi) (~1 lunar distance) of the Earth. During the close approach, the asteroid should peak at about apparent magnitude 7.3, and will be visible in binoculars.

1999 AN10 has a well determined orbit with an observation arc of 58 years. It was found by Andreas Doppler and Arno Gn├Ądig in precovery images from 1955. When 1999 AN10 only had an observation arc of 123 days, there was a 1 in 10 million chance that it could return on an impact trajectory in 2039.

On August 7, 1946, the asteroid passed 0.00625 AU (935,000 km; 581,000 mi) from Earth and then 0.00404 AU (604,000 km; 376,000 mi) from the Moon.
