This image below is a 4 frame animation of the asteroid 3200 Phaethon by Charles Bell (MPC Code H47). Phaethon is an Apollo Asteroid discovered on October 11, 1983 by Simon Green and John K. Davies examining the data from Infrared Astronomical Satellite (IRAS). Phaethon became the first asteroid discovered by a spacecraft.
One of Phaethon’s most remarkable distinctions is that it approaches the Sun closer than any other numbered asteroid; its perihelion is only 0.140 AU — less than half Mercury’s perihelion distance. It is a Mercury-, Venus-, Earth- and Mars-crosser.
Phaethon could be characterized as a comet, except it has been observed exhibiting a coma or tail. Soon after the discovery, Fred Whipple’s observation matched Phaethon’s orbital elements with the mean orbital elements of 19 Geminid meteors. Phaethon thus turned out to be the long-sought parent body of the Geminids meteor shower of mid-December
