Hunting for the Lunar Debris Hiding Near Earth

The Moon has a long history of being smacked by large rocks. Its pock-marked, cratered surface is evidence of that. Scientists expect that, as part of those impacts, some debris would be scattered into space – and that we should be able to track it down. But so far, there have been startlingly few discoveries of these Lunar-origin Asteroids (LOAs) despite their theoretical abundance. A new paper from Yixuan Wu and their colleagues at Tsinghua University explains why – and how the Vera Rubin Observatory might help with finding them.
