✨ Trivia
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 23.91 AU of the Sun — inside the orbit of Neptune.
- 🔁 One lap. A single orbit around the Sun takes it about 132 years.
- 🥏 How far it roams. Its orbit swings between 23.9 and 27.98 AU from the Sun.
Sense of scale
- 🧱 Sense of scale. In everyday terms it is about 3.6× the length of Manhattan island.
- 🚶 Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 6 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 77 km across.
What's in a name
- 🔢 Designation. Known only by its catalogue designation — no name yet.

About 2003 UC414
2003 UC414 is an uncommon kbo. It swings within 23.908 AU of the Sun at perihelion.
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.
How to see it
Like any astronomical target, 2003 UC414 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 2003 UC414 is an uncommon kbo
2003 UC414 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, Notably bright (low H), 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.
