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 4.88 AU of the Sun — inside the orbit of Jupiter.
- One lap. A single orbit around the Sun takes it about 238 years.
- How far it roams. Its orbit swings between 4.88 and 71.94 AU from the Sun.
Sense of scale
- Sense of scale. In everyday terms it is roughly 6.2× the height of Mount Everest.
- Walk around it. Walking its equator at a steady pace, eight hours a day, would take about 4.3 days.
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
- Size. Roughly 55.1 km across.

How to see it
Like any astronomical target, C/2011 KP36 (Spacewatch) 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/2011 KP36 (Spacewatch) is a common comet
C/2011 KP36 (Spacewatch) 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.
