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 1.04 AU of the Sun — inside the orbit of Mars.
- One lap. A single orbit around the Sun takes it about 5.4 years.
- How far it roams. Its orbit swings between 1.04 and 5.13 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is roughly 0.2× the height of Mount Everest.
Standing on it
- Don't jump. Escape velocity here is only around 0.84 m/s. A determined jump would launch you off it and into your own orbit around the Sun.
- 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.

How to see it
Like any astronomical target, 41P/Tuttle-Giacobini-Kresak 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.

Why 41P/Tuttle-Giacobini-Kresak is a common comet
41P/Tuttle-Giacobini-Kresak scores 19 points on Spacedle's rarity scale, which places it in the common tier. Another 3 points would lift it into a rarer tier.
That score comes from 3 science badges — Comet, 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.
