P/2013 R3 on November 15, 2013.
Hubble watched the slow disintegration of asteroid P/2013 R3 into 10 smaller pieces. The Hubble data revealed that the fragments are drifting away from each other at a leisurely one mile per hour — slower than the speed of a strolling human — which suggests the breakup is not the result of a collision.
