Trivia

What it actually is

  • Spectral class. Its spectrum reads M5 — 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 9.8 you'll want a small backyard telescope, over in Canis Minor.
  • Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
  • 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. Hopelessly far for any craft humanity can build today.

Getting there

  • Aboard Voyager 1. ≈ 217.9 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 19.4 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for Luyten's Star in the constellation CMi. At apparent magnitude 9.84, a small backyard telescope will bring it into view.

Like any astronomical target, Luyten's Star 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 Luyten's Star is a rare star

Luyten's Star scores 42 points on Spacedle's rarity scale, which places it in the rare tier. Another 8 points would lift it into a rarer tier.

That score comes from 6 science badges — Star, Nearby (<25 ly), Has a proper name, 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.
