Trivia

What it actually is

  • Spectral class. Its spectrum reads DA3 — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

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 13.4 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Pavo.
  • 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 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. ≈ 1.5 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 130.6 thousand years even at the Parker Solar Probe's 192 km/s.

About GL GJ 2149

GL GJ 2149 is an uncommon star. It lies about 83.6 light-years from Earth, sits in the constellation Pav, shines at apparent magnitude 13.4 and has spectral type DA3.

Its spectrum reads DA3 — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

How to see it

Look for GL GJ 2149 in the constellation Pav. At apparent magnitude 13.4, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 2149 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 2149 is an uncommon star

GL GJ 2149 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.

That score comes from 2 science badges — Star and White dwarf (a burnt-out core) — 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.
