Trivia
What it actually is
- Its orbit family. A trans-Neptunian object from the Kuiper Belt, out where the Sun is little more than the brightest star in a very dark sky.
- One lap. A single orbit around the Sun takes it about 49.4 thousand years.
- How far it roams. Its orbit swings between 64.74 and 2627.26 AU from the Sun.
- Wild orbit. Its highly elliptical path swings between scorching and frozen each lap.
Sense of scale
- Sense of scale. In everyday terms it is about 12.6× the length of Manhattan island.
- Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 21.5 days.
By the numbers
- Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 273 km across.
What's in a name
- Named. Notable enough to have earned a proper name, not just a catalogue number.

How to see it
Like any astronomical target, Leleakuhonua 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 Leleakuhonua is a rare kbo
Leleakuhonua scores 47 points on Spacedle's rarity scale, which places it in the rare tier. Another 3 points would lift it into a rarer tier.
That score comes from 5 science badges — Kuiper-belt object, Notably bright (low H), Has a proper name, Trans-Neptunian object and Far-flung orbit (a > 50 AU) — 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.
