NASA spacecraft discovers tiny moon around asteroid during close flyby

Really exciting to see the pictures. I helped write code for a paper predicting the size of Dinkinesh a few weeks before the flyby. It's so small we had to overlay multiple images in order to even see it in IR. We did not expect a binary!

Fascinating discovery. Space reporting like this never fails to light up my imagination. I wonder what it would be like to hang out on the surface of the parent asteroid and watch as the relatively small moon floats by overhead - so close that you could probably jump from one to the other.
