P/2010 A2 is the 5th recognised Main Belt Comet (MBC). It differs from the others in having an orbit within the hot, inner regions of the asteroid belt. The morphology suggests - but does not prove - a recent collisional origin. We cannot rule out the possibility that P/2010 A2 is driven by ice sublimation, as is MBC prototype 133P/Elst-Pizarro, or by an undetermined process.

Trail of dust may point to fresh violence in asteroid belt

A mysterious streak of dust in the asteroid belt might represent the first evidence of a collision between asteroids in modern times.
Using a telescope in New Mexico, an asteroid survey called LINEAR (Lincoln Near Earth Asteroid Research), spotted a long dust trail on 6 January.
The dust trail, called P/2010 A2, resembles a comet's tail, but unlike most comets, it resides in the asteroid belt between Mars and Jupiter.

Something awfully curious is happening 250 million miles away in the asteroid belt.
Nothing quite like it has ever been seen before.
There's a newly discovered object that superficially looks like a comet but lives among the asteroids.
One possibility is that we are witnessing a never-before-seen collision between two asteroids that ejected a dust plume.
