About this page

Selene Notes is a small, hobby reading page about the Moon. It is written for curious readers, students and anyone who has looked up on a clear night and wondered how far away that bright disc really is.

The page is static and light by design: no accounts, no tracking, no advertising and no cookies. Numbers are rounded averages and are meant as an introduction rather than a scientific reference.

Further reading

For current missions and data, the public pages of NASA's Lunar Reconnaissance Orbiter team, the ESA exploration programme and the national space agencies listed in the footer are excellent starting points.
