Trivia

What it actually is

  • Spectral class. Its spectrum reads Rpvar — a carbon star, wrapped in so much soot that its light is filtered to a deep ruby red.
  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

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 9.6 you'll want a small backyard telescope, 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. Impossible with our current technology — and the next millennium of it.

Getting there

  • Aboard Voyager 1. ≈ 25.9 million years at Voyager 1's speed (17 km/s).

About HIP 39376

HIP 39376 is an uncommon variable star. It lies about 1,475.8 light-years from Earth, sits in the constellation Pup, shines at apparent magnitude 9.55 and has spectral type Rpvar.

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

How to see it

Look for HIP 39376 in the constellation Pup. At apparent magnitude 9.55, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 39376 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 HIP 39376 is an uncommon variable star

HIP 39376 scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.

That score comes from 4 science badges — Variable star, Distant (over 1,000 light-years), Strongly variable and A named variable star — 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.
