(3366) Gödel , internationally also (3366) Godel , is an asteroid of the outer main belt , which was discovered on September 22, 1985 by the Swiss astronomer Thomas Schildknecht from the Zimmerwald Observatory of the University of Bern .
The asteroid was named in honor of the Austrian - American mathematician Kurt Gödel (1906–1978), whose ideas Thomas Schildknecht accompanied through many nights of observation.
It belongs to the Eos asteroid family named after (221) Eos . This is one of the first three asteroid groups described by the Japanese astronomer Kiyotsugu Hirayama in 1918, which is one of the largest with around 4400 asteroids. This group of asteroids typically has large semiaxes from 2.95 to 3.1 AU , orbital inclinations between 8 ° and 12 ° and is limited inwardly by the Kirkwood gap of the 7: 3 resonance with Jupiter . It is believed that the family was created by a collision about 1.1 billion years ago.
