Tycho City

From Memory Alpha, the free Star Trek reference.

Tycho City was located on Earth's Moon and probably part of the Lunar colonies. The city had self-contained atmosphere and artificial gravity.

Cadet Dorian Collins was from Tycho City. (DS9: "Valiant")

By 2373, it was large enough to be seen from Earth at daytime, since Commander William T. Riker missed the familiar sight of the city, while looking at the Moon during his mission to the year 2063. (Star Trek: First Contact)

[edit] Background

The city was likely named either after the Danish astronomer Tycho Brahe of the 16th century, or the lunar crater Tycho. It may be related to the Tycho Base of the 22nd century.
