Trivia
What it actually is
- Its orbit family. A Jupiter-family comet, herded by Jupiter's gravity into a short orbit of under twenty years.
- Closest approach. At its nearest it comes within 6.01 AU of the Sun — inside the orbit of Saturn.
- Wild orbit. Its highly elliptical path swings between scorching and frozen each lap.
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/2004 P1 (NEAT) 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/2004 P1 (NEAT) is a rare comet
C/2004 P1 (NEAT) scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.
That score comes from 5 science badges — Comet, Has a proper name, Jupiter-family comet, 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.
