Trivia
What it actually is
- Its address. It orbits about 42.02 AU from the Sun — roughly 42 times Earth's distance.
- Off the beaten plane. Its orbit is tilted 24° out of the flat plane the planets share — half of every lap is spent above the others, half below.
- Around its planet. It circles its planet at a distance of 5619 km — about 1% of the Earth–Moon gap — coming right round once every 5.5 days.
Sense of scale
- Against Earth. It is only 2% of Earth's width — you could pack about 88.4 thousand of it inside our planet.
- Against our Moon. Smaller than our own Moon — about 8% of its width.
- Ground to cover. Its whole surface adds up to about 257 thousand km² — roughly 163.5 times the area of Greater London.
- Walk around it. Walking right round its equator, eight hours a day, would take about 22.5 days.
Time and light
- Sunrise is late. Sunlight takes about 5.8 hours to get there, against eight minutes to reach us.

How to see it
Like any astronomical target, Actaea 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 Actaea is an uncommon moon
Actaea 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.
