A satellite of a closely approaching asteroid could be moving in any
direction relative to the Earth. However, 2012 DA14 was several
hundred thousand kilometers away from the meteoroid, orders of
magnitude more than the typical distance of an asteroid moon.
Asteroid 2012 DA14 was very small, with a very low escape velocity.
