Asteroid named after Randall "XKCD" Munroe

Holy. Smokes. Randall "XKCD" Munroe has had an asteroid named after him. Good old 4292 is big enough to wipe out life on Earth, but alas, its Mars/Jupiter orbit is boringly stable. Still, there's hope it will decay eventually, and create the splash Randy deserves!

Amazing xkcd readers Lewis Hulbert and Jordan Zhu noticed that the International Astronomical Union—the organization in charge of official astronomical naming—was taking suggestions for what to name small Solar System objects. They submitted my name for asteroid (4942) 1987 DU6, and it was subsequently renamed 4942 Munroe.

I’m really touched. I spent all weekend telling everyone who wanted to listen (and probably some who didn’t) about the asteroid.

The first thing I did was try to figure out whether 4942 Munroe was big enough to pose a threat to Earth. I was excited to learn that, based on its albedo (brightness), it’s probably about 6-10 kilometers in diameter. That’s comparable in size to the one that killed the dinosaurs—definitely big enough to cause a mass extinction!
