Trivia
Hard to believe
- Round under its own weight. Big enough that its own gravity has pulled it into a sphere — most of its neighbours are potato-shaped rubble.
What it actually is
- Its address. It orbits about 1 AU from the Sun — about the same as Earth's distance.
- Almost a perfect circle. Its orbit is very nearly circular — rounder than Earth's, so it gets the same amount of sunlight all year round.
- Around its planet. It circles its planet at a distance of 384.4 thousand km — about the same as the Earth–Moon gap — coming right round once every 27.3 days.
- It runs the tides. Its gravity is what raises Earth's tides — and the friction of those tides is pushing it away from us by about 3.8 cm a year.
Sense of scale
- Against Earth. It is only 27% of Earth's width — you could pack about 49.3 of it inside our planet.
- Ground to cover. Its whole surface adds up to about 37.9 million km² — about 25% of Earth's dry land.
- Walk around it. Walking right round its equator, eight hours a day, would take about 9 months.

How to see it
Like any astronomical target, Moon is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. Because it moves against the background stars, the live position panel on this page tracks where it is right now. The visibility panel above works out tonight's viewing window for your saved location.
Why Moon is an epic moon
Moon scores 64 points on Spacedle's rarity scale, which places it in the epic tier. Another 14 points would lift it into a rarer tier.
That score comes from 4 science badges — Moon, Has a proper name, Earth's Moon and Tidally locked — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
