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.
- Closest approach. At its nearest it comes within 28.99 AU of the Sun — inside the orbit of Neptune.
- One lap. A single orbit around the Sun takes it about 245 years.
- How far it roams. Its orbit swings between 28.99 and 49.27 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 10.2× the length of Manhattan island.
- Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 17.3 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 220 km across.
What's in a name
- Designation. Known only by its catalogue designation — no name yet.

Why (728216) 2010 LB136 is an uncommon kbo
(728216) 2010 LB136 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points 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 Trans-Neptunian object — 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.
