Trivia
What it actually is
- Its orbit family. An outer main-belt asteroid, out towards Jupiter where the rocks grow darker and richer in carbon and ice.
- Closest approach. At its nearest it comes within 2.97 AU of the Sun — inside the orbit of Jupiter.
- One lap. A single orbit around the Sun takes it about 6.3 years.
- How far it roams. Its orbit swings between 2.97 and 3.84 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is about 11× the length of Manhattan island.
- Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 18.6 days.
Standing on it
- Sunlight there. Even at its closest the sunlight is only about 11% as strong as Earth's.
By the numbers
- Size. Roughly 237 km across.

How to see it
Like any astronomical target, Cybele 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 Cybele is a rare asteroid
Cybele scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.
That score comes from 6 science badges — Asteroid, Large body (100-500 km), Notably bright (low H), Has a proper name, Main-belt asteroid and Metal-rich asteroid — 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.
