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 Jupiter-family comet, herded by Jupiter's gravity into a short orbit of under twenty years.
- Closest approach. At its nearest it comes within 1.11 AU of the Sun — inside the orbit of Mars.
- One lap. A single orbit around the Sun takes it about 8.7 years.
- How far it roams. Its orbit swings between 1.11 and 7.33 AU from the Sun.
Standing on it
- Growing a tail. Once inside roughly the orbit of Mars the ice starts turning straight to gas, blowing out the coma and tail that make a comet a comet.
- 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.

How to see it
Like any astronomical target, 333P/LINEAR 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 333P/LINEAR is an uncommon comet
333P/LINEAR scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.
That score comes from 4 science badges — Comet, Retrograde orbit, Has a proper name and Jupiter-family comet — 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.
