6R 10DB9

6R 10DB9 is small a Météoroïde from approximately 4 Mètre S of diameter, which with the June 20th 2007 was temporarily in Orbite around the Ground.

This celestial body should be ejected of its terrestrial orbit after July 2007, after having made four orbits around the Ground for one total length of time of approximately a year. Even if the Ground has during this time a second Natural satellite, its designation of “second the moon” remains temporary. In a general way, 6R 10DB9 would be rather Astéroïde geocroisor, possibly a Aten.

History

6R 10DB9 was discovered the September 14th 2006 by the Catalina Sky Survey in Arizona, with the the United States. Preliminary orbital calculations indicated that it had been captured by terrestrial gravity since one period a solar orbit of approximately 11 months, a behavior similar to several stages of rockets dating from the Programme Apollo. However, of the later analyzes showed that the object was affected by the pressure of the solar radiation in such way that it was to be a question of a dense rock object.

The June 14th 2007, the asteroid was with its fourth Périgée of the year 2007, at a distance from approximately 0,7 times that between the Ground and the the Moon. Because of its small size, the confirmation that this small asteroid is well a natural body was given only to this moment.

6R 10DB9 should be ejected terrestrial orbit towards a solar orbit in July 2007. It could pass by again close to the Ground in 2028.

Orbits

At the time of its discovery the September 14th 2006, 6R 10DB9 was located at 2,2 times the distance Ground - the Moon and moved away from planet. Later calculations indicated that before its approach, it was located on a solar orbit of 1,04 ua of Equatorial radius, tilted of 1°, for a period of 1,06 year: an orbit very similar to that of the Ground.

Since its discovery, the Périgée S following were observed:

6R 10DB9 approached the Earth in 1958, 1969, 1979 and 1992. It should pass by again in 2028.
