3122 Florence has 2 moons!!

Goldstone radar observed Florence during recently flyby of earth and saw this:

One wouldn't think so puny an asteroid has enough gravity to make a satellite go around it in 8 hours. The presence of the satellite perhaps puts some upper limit on how close Florence has ever come to the earth or the moon, because I suspect a sufficiently close passage to the earth or the moon will strip those satellites from Florence.
