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 305 years.
- How far it roams. Its orbit swings between 39.74 and 50.88 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 7× the length of Manhattan island.
- Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 11.8 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 150 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, Logos 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 Logos is an epic kbo
Logos scores 55 points on Spacedle's rarity scale, which places it in the epic tier. Another 23 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 Spinning past the rubble-pile limit — 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.
