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 19.19 AU from the Sun — roughly 19.2 times Earth's distance.
- Around its planet. It circles its planet at a distance of 583.5 thousand km — roughly 1.5 times the Earth–Moon gap — coming right round once every 13.5 days.
Sense of scale
- Against Earth. It is only 12% of Earth's width — you could pack about 586 of it inside our planet.
- Against our Moon. Smaller than our own Moon — about 44% of its width.
- Ground to cover. Its whole surface adds up to about 7.3 million km² — about 5% of Earth's dry land.
- Walk around it. Walking right round its equator, eight hours a day, would take about 3.9 months.
Time and light
- Sunrise is late. Sunlight takes about 2.7 hours to get there, against eight minutes to reach us.

How to see it
Like any astronomical target, Oberon 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 Oberon is an uncommon moon
Oberon scores 30 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 4 points would lift it into a rarer tier.
That score comes from 3 science badges — Moon, Has a proper name 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.
