Trivia

What it actually is

  • Spectral class. Its spectrum reads Mp — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.

Sense of scale

  • In perspective. Inside our stellar backyard: every radio broadcast humanity has ever made has already swept past it.

Find it in the sky

  • How to spot it. At magnitude 11.8 you'll want a small backyard telescope, over in Ara.
  • 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 June — 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. ≈ 211.9 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 18.8 thousand years even at the Parker Solar Probe's 192 km/s.

About HIP 82724

HIP 82724 is a rare star. It lies about 12.1 light-years from Earth, sits in the constellation Ara, shines at apparent magnitude 11.85 and has spectral type Mp.

Its spectrum reads Mp — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.

How to see it

Look for HIP 82724 in the constellation Ara. At apparent magnitude 11.85, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 82724 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 82724 is a rare star

HIP 82724 scores 40 points on Spacedle's rarity scale, which places it in the rare tier. Another 10 points would lift it into a rarer tier.

That score comes from 6 science badges — Star, Nearby (<25 ly), Cool red M-type star, Deep red star, Red dwarf and Intrinsically feeble (Mv > +12) — 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.
