Trivia

What it actually is

  • Spectral class. Its spectrum reads G8II — a G-type star: the very same spectral class as our own Sun.
  • Where it is in life. It is a bright giant, well on its way to the largest stars there are.

Sense of scale

  • In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

  • How to spot it. At magnitude 5.1 you can see it with your own eyes from a dark site, over in Puppis.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around January — that's when to go looking.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 15.1 million years at Voyager 1's speed (17 km/s).

How to see it

Look for 12 Pup in the constellation Pup. At apparent magnitude 5.09, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, 12 Pup 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. The visibility panel above works out tonight's viewing window for your saved location.

Why 12 Pup is a rare star

12 Pup scores 41 points on Spacedle's rarity scale, which places it in the rare tier. Another 9 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Naked-eye visible, Sun-like G-type star, Bright giant and Intrinsically luminous (Mv < −2) — 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.
