Trivia

What it actually is

  • Spectral class. Its spectrum reads C(R) — 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 11.2 you'll want a small backyard telescope, over in Norma.
  • 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 May — 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. ≈ 2.1 million years at Voyager 1's speed (17 km/s).

About HIP 80365

HIP 80365 is an epic variable star. It lies about 119.5 light-years from Earth, sits in the constellation Nor, shines at apparent magnitude 11.18 and has spectral type C(R).

Its spectrum reads C(R) — 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 80365 in the constellation Nor. At apparent magnitude 11.18, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 80365 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 80365 is an epic variable star

HIP 80365 scores 52 points on Spacedle's rarity scale, which places it in the epic tier. Another 26 points would lift it into a rarer tier.

That score comes from 4 science badges — Variable star, Carbon star (sooty red), Dramatic variable (over 2 magnitudes) 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.
