Research published in 2007 concludes that the impactor which created Tycho came from a enormous collison between two asteroids in the main asteroid belt, some 160 million years ago.1 This collision, the research suggests, also produced the impactor which struck the Earth 65 million years ago and gave rise to the Chicxulub crater and the devastating mass extinction in which the last of the dinosaurs died out. See the Chicxulub crater article for more details.
Science fiction connectionsTycho features in the film and book 2001: A Space Odyssey as the location of TMA-1 (Tycho Magnetic Anomaly 1) which turns out to be one of the enigmatic monoliths placed in the solar system by an alien civilization. In the story, Dr. Heywood Floyd travels from Clavius Base to see the artifact. Tycho also serves as the location of a 24th century community called Tycho City in the film Star Trek: First Contact.
