Tycho Brahe was a famous astronomer of the 16th century.
In 2151, Jonathan Archer created a distraction for Commander Trip 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 crater, Tycho Base, and Tycho City were named after him. Brahe was one of the fathers of modern astronomy working before the creation of telescopes. He spent years documenting the motion of the planets, leading to Kepler's laws of planetary motion. ("The Andorian Incident", text commentary, ENT Season 1 DVD special feature)
