Trivia

What it actually is

  • Spectral class. Its spectrum reads M3 — 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. 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 13.2 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Cepheus.
  • Never sets. So far north that from Britain, Canada or northern Europe it never dips below the horizon — it is up every clear night of the year.
  • Best time of year. It stands highest in the middle of the night around August — 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. ≈ 5.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 485.9 thousand years even at the Parker Solar Probe's 192 km/s.

About HIP 102976

HIP 102976 is an uncommon star. It lies about 311.2 light-years from Earth, sits in the constellation Cep, shines at apparent magnitude 13.21 and has spectral type M3.

Its spectrum reads M3 — 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 102976 in the constellation Cep. At apparent magnitude 13.21, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, HIP 102976 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 102976 is an uncommon star

HIP 102976 scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Never sets (northern circumpolar), Cool red M-type star, Deep red star and Red dwarf — 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.
