✨ Trivia
What it actually is
- 🛸 Its orbit family. A long-period comet falling in from the Oort Cloud, where it spent billions of years in the deep freeze before something nudged it loose.
- 🌞 Closest approach. At its nearest it comes within 2.37 AU of the Sun — inside the orbit of Jupiter.
- 🔁 One lap. A single orbit around the Sun takes it about 116.8 thousand years.
- 🥏 How far it roams. Its orbit swings between 2.39 and 4775.61 AU from the Sun.
Standing on it
- 🥶 Sunlight there. Even at its closest the sunlight is only about 18% as strong as Earth's.
- ☄️ Tail. Its tail always points away from the Sun, never trailing behind its motion — it is blown, not dragged.
By the numbers
- 🧊 Made of. A comet is a dirty snowball: water ice, frozen carbon dioxide and dust, held together loosely enough that some simply crumble when the Sun warms them.
What's in a name
- 🏷️ Named. Notable enough to have earned a proper name, not just a catalogue number.

About C/2023 C2 (ATLAS)
C/2023 C2 (ATLAS) is an uncommon comet. It swings within 2.368 AU of the Sun at perihelion.
A long-period comet falling in from the Oort Cloud, where it spent billions of years in the deep freeze before something nudged it loose.
How to see it
Like any astronomical target, C/2023 C2 (ATLAS) 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 C/2023 C2 (ATLAS) is an uncommon comet
C/2023 C2 (ATLAS) scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.
That score comes from 4 science badges — Comet, Has a proper name, Far-flung orbit (a > 50 AU) and Steeply tilted orbit (i > 40°) — 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.
