Trivia
What it actually is
- Its address. It orbits about 43.13 AU from the Sun — roughly 43.1 times Earth's distance.
- A lopsided orbit. Its path is distinctly off-centre: it swings between 34.72 and 51.54 AU from the Sun, so its seasons are driven as much by distance as by tilt.
- Off the beaten plane. Its orbit is tilted 28° 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 49.9 thousand km — about 13% of the Earth–Moon gap — coming right round once every 49.1 days.
Sense of scale
- Against Earth. It is only 3% of Earth's width — you could pack about 63.1 thousand of it inside our planet.
- Against our Moon. Smaller than our own Moon — about 9% of its width.
- Ground to cover. Its whole surface adds up to about 321.7 thousand km² — roughly 204.6 times the area of Greater London.
- Walk around it. Walking right round its equator, eight hours a day, would take about 25.1 days.

How to see it
Like any astronomical target, Hi'iaka 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 Hi'iaka is an uncommon moon
Hi'iaka 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.
