is an Apollo near-Earth asteroid and potentially hazardous object. It was discovered on 8 March 2003 by LPL/Spacewatch II at an apparent magnitude of 20 using a reflecting telescope. It has an estimated diameter of . The asteroid was listed on Sentry Risk Table with a Torino Scale rating of 1 on 2 April 2003.
Description
Many of the virtual impactors were located near the nominal orbital solution and the asteroid has a low inclination relative to Earth's orbit. Observation by the Very Large Telescope (VLT) 8 meter facilities on 22 May and 19 June 2003 when was very dim with an apparent magnitude between 24–25At an apparent magnitude of 24, the asteroid was roughly 10 million times fainter than can be seen with the naked eye.Math: refined the orbit. It was removed from the Sentry Risk Table on 28 May 2003.
has the smallest Earth Minimum orbit intersection distance (MOID) of any known potentially hazardous asteroid. The Earth MOID is . Asteroids with a smaller Earth MOID are less than ~100 meters in diameter such as and . Earth impactors and 2014 AA had small Earth MOID values as they were on their impact approach when discovered. +Close-approaches to Earth Date Distance from Earth 2014-07-01 (37.6 LD) 2041-07-01 (38.6 LD) 2067-01-31 (34.0 LD) 2094-01-30 (29.1 LD) 2122-07-04 (28.9 LD) 2149-07-06 (20.2 LD) 2175-02-02 (31.2 LD)
