(276033) 2002 AJ 129 is an asteroid whose orbit around the sun regularly crosses the orbits of the inner planets of the solar system ( Mercury , Venus , Earth and Mars ).
description
The object was discovered on January 15, 2002 in the Near Earth Asteroid Tracking Program (NEAT) of the Jet Propulsion Laboratory (JPL) at the Haleakala Observatory on Maui . Nine days later, it approached Earth to a distance of 0.3364 AU (about 50 million km). The earth orbit cruiser is of the Apollo asteroid type , its orbital period is 586 days and 9 hours.
The size of this celestial body is estimated to be around 400 to 1200 meters in diameter, nothing is known about its composition. Due to its mass, its orbit and the high orbital speed of 24 to 51 km / s, it is considered a potentially dangerous asteroid.
On the occasion of the approach to earth on February 4, 2018, which will bring it up to a distance of 0.028127 AU (around 4.2 million kilometers, eleven times the lunar distance ) at 21:31 UTC, the plan was to move the object between 3 . and 7 February 2018 the Goldstone - radio telescope and Arecibo observed.
Approximations
The future approximations were calculated in 2011 for almost 200 years in advance. At a shorter distance than 2018, the asteroid will only pass Earth in this century in 2087.
A collision need not be expected in this century, as the distance will be more than ten times the lunar distance. For the year 2172, however, a much narrower passage is expected with a distance of only about 685,600 km, that is one and a half times the distance between the earth and the moon .
