Selene was the ancient Greek goddess of the Moon. You might be confused by this, as you might find that Artemis and Diana were known as the goddess of the Moon, too, and sometimes Cynthia was used as well! Definitely confusing. Modern science doesn’t help with a selenographer being a person who maps the Moon, but a spacecraft may reach pericynthion, the closest point in its orbit to the Moon (orbits are usually elliptical to some degree, as a perfectly circular orbit is not a very stable shape in orbital mechanics.) However, I’d much rather be known as a selenophile than a lunatic, any day – or night.
