Trivia
What it actually is
- Its address. It orbits about 9.54 AU from the Sun — roughly 9.5 times Earth's distance.
- Around its planet. It circles its planet at a distance of 1.5 million km — roughly 3.9 times the Earth–Moon gap — coming right round once every 21.3 days.
Sense of scale
- Against Earth. It is only 2% of Earth's width — you could pack about 105.1 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 229 thousand km² — roughly 145.7 times the area of Greater London.
- Walk around it. Walking right round its equator, eight hours a day, would take about 21.2 days.
Time and light
- Sunrise is late. Sunlight takes about 79.3 minutes to get there, against eight minutes to reach us.
Standing on it
- Sunlight there. Sunlight is about 90.9 times weaker there than at Earth.

How to see it
Like any astronomical target, Hyperion 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 Hyperion is an uncommon moon
Hyperion scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.
That score comes from 2 science badges — Moon and Has a proper name — 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.
