✨ Trivia
Hard to believe
- 🔄 Against the traffic. It goes round the Sun backwards, against the direction every planet and almost everything else travels.
What it actually is
- 🛸 Its orbit family. A centaur, wandering between the orbits of Jupiter and Neptune on a path nothing can stabilise. Half asteroid and half comet, and gone from this orbit within a few million years.
- 🌞 Closest approach. At its nearest it comes within 4.46 AU of the Sun — inside the orbit of Jupiter.
- 🔁 One lap. A single orbit around the Sun takes it about 46.8 years.
- 🥏 How far it roams. Its orbit swings between 4.46 and 21.52 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is roughly 0.8× the height of Mount Everest.
By the numbers
- 📐 Estimated size. Nobody has measured its size directly. Assuming it reflects light like a typical asteroid, its brightness implies something roughly 7.3 km across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.

Why (771532) 2016 JK24 is an uncommon kbo
(771532) 2016 JK24 scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Kuiper-belt object, Retrograde orbit, Catalogue designation only and Centaur: adrift between the giants — 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.
