Trivia

What it actually is

  • Spectral class. Its spectrum reads m — 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 14.7 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Libra.
  • 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 April — 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. ≈ 1.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 121.3 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for GL GJ 3847 in the constellation Lib. At apparent magnitude 14.7, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 3847 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 GL GJ 3847 is a trash star

GL GJ 3847 scores 12 points on Spacedle's rarity scale, which places it in the trash tier. Another 3 points would lift it into a rarer tier.

That score comes from 3 science badges — Star, On the zodiac 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.
