When is an asteroid not an asteroid? When it's Elon Musk's Tesla Roadster, it turns out.

What the article doesn't say is indicated by the asteroid designation: the "discovery" was based on a new identification in old (2018) observations. If you open the discovery announcement, it can be seen that the object was identified in photos from February 8 (the day of the launch) to February 18, 2018. It's quite impressive really that it could be observed for ten days.
 
So, what is the probability that "Starman" will "drive" Elon's roadster into Earth at some point in the future? And, would it be expected to completely burn up during reentry, or would parts like the motors be available to crash through the roof of somebody in Florida, too?

This is the headliner for today? Not the article about a newly discovered form of magnetism?

I've read articles about this and I'm not convinced that this is a discovery of a new form of magnetism. It's probably just that antiferromagnets haven't been studied well enough at all, and their magnetic moments and directions vary around average values, also depending on external influences, and are not hard numbers.

Indeed, and I'll reserve excitement pending applications of it. Point being, it's still more interesting and newsworthy than lamenting the existence of a single Tesla Roadster in orbit.
