Main character of the book "The Green Futures of Tycho" by William Sleator. In the book his parents named him after the astronomer Tycho Brahe.

Tycho is the name of a prominent impact crater on the surface of the moon. It was named after Tycho Brahe, and its rim was the landing site of the 1968 robotic Surveyor 7 mission. Tycho has sharply defined edges, being pretty "young" for a big crater--only about 100 million years old. This makes Tycho easy to spot: It's in the southern lunar highlands and it's surrounded by smaller craters and well-known ray system (fragmented material from the original impact). Tycho's rays have been depicted on lunar maps since the mid-1600s and are up to 1500 km long.
