Trivia
What it actually is
- Its orbit family. A Chiron-type comet, orbiting out among the giant planets rather than diving into the inner Solar System.
- Closest approach. At its nearest it comes within 6.2 AU of the Sun — inside the orbit of Saturn.
- One lap. A single orbit around the Sun takes it about 20.6 years.
- How far it roams. Its orbit swings between 6.2 and 8.81 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.

The visibility panel above works out tonight's viewing window for your saved location.
Why P/2005 T3 (Read) is a rare comet
P/2005 T3 (Read) 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 4 science badges — Comet, Has a proper name, Chiron-type comet 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.
