(137108) 1999 AN10

[5] On 7 August 2027, this asteroid will pass at about 0.00261 AU (390,000 km; 243,000 mi; 1.02 LD) of the Earth's center.

[6][1][7][8] During the close approach, it is expected to peak at about apparent magnitude 7.3,[9] and will be visible in binoculars.

1999 AN10 has a well-determined orbit with an observation arc of 65 years.

[1] It was found by Andreas Doppler and Arno Gnädig in precovery images from 1955.

[1] When astronomers had an observation arc of the object of 123 days, computations gave a 1 in 10 million chance it would return on an impact trajectory in 2039.
