Trivia

What it actually is

  • Spectral class. Its spectrum reads M0 — 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 10.7 you'll want a small backyard telescope, over in Draco.
  • 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 July — 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. ≈ 2.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 198 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for HIP 91906 in the constellation Dra. At apparent magnitude 10.71, a small backyard telescope will bring it into view.

Like any astronomical target, HIP 91906 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 91906 is a common star

HIP 91906 scores 18 points on Spacedle's rarity scale, which places it in the common tier. Another 4 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Never sets (northern circumpolar), Cool red M-type 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.
