- The Apparent magnitude of the Moon is −2.5 to −12.9,−12.74 (mean full moon).
- The angular diameter of the Moon is 29.3 to 34.1 arcminutes.
- The three primary gases in the lunar atmosphere are neon, helium, and hydrogen, in roughly equal amounts. Small amounts of methane, carbon dioxide, ammonia, and water were also detected.
- The moon's surface is covered with dead volcanoes, impact craters, and lava flows, some visible to the unaided stargazer. Early scientists thought the dark stretches of the moon might be oceans, and so named such features mare, which is Latin for "seas" (maria when there are more than one).
