Trivia

What it actually is

  • Spectral class. Its spectrum reads DC: — 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 11.5 you'll want a small backyard telescope, over in Musca.
  • 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 March — 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. ≈ 264.1 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 23.5 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for GL Gl 440 in the constellation Mus. At apparent magnitude 11.5, a small backyard telescope will bring it into view.

Like any astronomical target, GL Gl 440 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 Gl 440 is a rare star

GL Gl 440 scores 43 points on Spacedle's rarity scale, which places it in the rare tier. Another 7 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Nearby (<25 ly), White dwarf (a burnt-out core) 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.
