Trivia
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 12.2 million km, roughly 31.7 times the Earth–Moon gap.
Sense of scale
- Ground to cover. Its whole surface adds up to about 80.4 thousand km² — roughly 51.2 times the area of Greater London.
- Walk around it. Walking right round its equator, eight hours a day, would take about 12.6 days.
Time and light
- Sunrise is late. Sunlight takes about 2.7 hours to get there, against eight minutes to reach us.
Standing on it
- Sunlight there. Sunlight is about 368 times weaker there than at Earth.
- A year here. It rides around the Sun with its planet, one full lap every 84 Earth years.
By the numbers
- Size. About 160 km across — about 7.4× the length of Manhattan island.

How to see it
Like any astronomical target, Sycorax 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 Sycorax is a rare moon
Sycorax scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.
That score comes from 3 science badges — Moon, Has a proper name and Orbits backwards around its planet — 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.
