About C/2024 G2 (ATLAS)
C/2024 G2 (ATLAS) is a rare comet. It swings within 5.348 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.

Trivia
Hard to believe
- Against the traffic. It goes round the Sun backwards, against the direction every planet and almost everything else travels.
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 5.35 AU of the Sun — inside the orbit of Saturn.
- One lap. A single orbit around the Sun takes it about 19.6 thousand years.
- How far it roams. Its orbit swings between 5.31 and 1450.69 AU from the Sun.
Standing on it
- 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.

How to see it
Like any astronomical target, C/2024 G2 (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/2024 G2 (ATLAS) is a rare comet
C/2024 G2 (ATLAS) scores 46 points on Spacedle's rarity scale, which places it in the rare tier. Another 4 points would lift it into a rarer tier.
That score comes from 5 science badges — Comet, Retrograde orbit, Has a proper name, Far-flung orbit (a > 50 AU) and Never comes near the Sun — 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.
