A random thing to know

Except for the Maxwell Montes mountain range, named for James Clerk Maxwell, all geographic features on the surface of the planet Venus are named after women (both fictional and historical).  The reason for this is that the Maxwell Montes mountain range was the only feature large enough to be discernable through Venus' dense atmosphere using radio telescopes in the 1960's.  It wasn't until the early 1990's that the Magellan space probe was able to provide detailed radio images of 98% of Venus's surface.  Rather than labeling the more prominant features one-by-one as they were spotted (normally after their discoverers), nearly the entire surface of the planet was suddenly laid bare.  As we eagerly mapped out the mountains and valleys of Venus, it seemed only fitting to give them feminine names.
