Tycho Brahe was a famous Danish astronomer of the 16th century. In 2151, Jonathan Archer created a diversion for Commander Tucker, both of whom were being held captive by Andorians, by telling the Andorians of Brahe losing his nose in a duel over a math equation. (ENT: "The Andorian Incident") Tycho City and Tycho Base on the moon may have been directly named for him, or for the notable Lunar crater also named after him, Tycho crater.
