Trivia

What it actually is

  • Spectral class. Its spectrum reads C6II — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
  • 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 9.5 you'll want a small backyard telescope, over in Hydrus.
  • Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
  • Best time of year. It stands highest in the middle of the night around September — 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. ≈ 5.9 million years at Voyager 1's speed (17 km/s).

About HD 2432

HD 2432 is a rare star. It lies about 338 light-years from Earth, sits in the constellation Hyi, shines at apparent magnitude 9.52 and has spectral type C6II.

Its spectrum reads C6II — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.

How to see it

Look for HD 2432 in the constellation Hyi. At apparent magnitude 9.52, a small backyard telescope will bring it into view.

Like any astronomical target, HD 2432 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 HD 2432 is a rare star

HD 2432 scores 39 points on Spacedle's rarity scale, which places it in the rare tier. Another 11 points would lift it into a rarer tier.

That score comes from 3 science badges — Star, Carbon star (sooty red) and Bright giant — 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.
