ASTEROID comments:
1: soln ref.= JPL#11, OCC=1
2: source=ORB
These are two graphs showing the movement of the asteroid in a frame of reference co-rotating
with earth
Sun is at (0,0) and Earth is at (1,0).
In this moment, the asteoroid seems a quasi-satellite of earth
However, the libration seems quite fast, so the "quasi-satellite" status is absolutely
temporary:
Cheers,
