The mysterious Earth approaching object Phaethon (FAY-eh-thon) does not fit neatly into our definition of either an asteroid or a comet. Further it appears to be like the Peanuts character Pigpen in that it leaves a trail of dust and other fine debris in it's wake which in the case of Phaethon produces the Geminid Meteor Shower to delight us every year around Christmas time. Phaethon is amazing in that every 524 days it makes a death defying flight to a point less than one of half of the planet Mercury's distance from the Sun, where it's surface temperature reaches a mind boggling 1,200 Fahrenheit. During one of these events the NASA Stereo Spacecraft A discovered that Phaethon had rock dust tail.
