NASA's STEREO A spacecraft captured the rock comet Phaethon just as it passed through perihelion. 3200 Phaethon is an active Apollo asteroid with an orbit that brings it closer to the Sun than any other named asteroid. For this reason, it was named after the Greek myth of Phaëthon, son of the sun god Helios. It is 5.8 km (3.6 mi) in diameter and is the parent body of the Geminids meteor shower of mid-December.
