Asteroid 42355, Typhon, was discovered on February 5, 2002 by the NEAT program at Palomar Observatory near Pauma Valley, California. The NEAT program gets the discovery credit. Typhon has a period of 232 years, 162 days and is about 99 miles in diameter.
It was named for a monster of Greek mythology who was the god of destructive volcanism, earthquakes, and hot dangerous storm winds and attempted to overthrow Zeus, who defeated him by piling Mount Etna on top of him.
Typhon has a companion, known as Echidna, after the mother of many of the major monsters of Greek mythology. Echidna is about 58 miles in diameter.
Jonathan Dunn has linked Typhon to power struggles, battles with the system, the triumph of the will. Henk Middelraad has linked it to infighting.
