Trivia

What it actually is

  • Spectral class. Its spectrum reads DA7 — 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 12.8 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Cetus.
  • 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 October — 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. ≈ 704.1 thousand years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 62.6 thousand years even at the Parker Solar Probe's 192 km/s.

About GL Gl 64

GL Gl 64 is an uncommon star. It lies about 40.1 light-years from Earth, sits in the constellation Cet, shines at apparent magnitude 12.84 and has spectral type DA7.

Its spectrum reads DA7 — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

How to see it

Look for GL Gl 64 in the constellation Cet. At apparent magnitude 12.84, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL Gl 64 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 64 is an uncommon star

GL Gl 64 scores 31 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 3 points would lift it into a rarer tier.

That score comes from 3 science badges — Star, 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.
