Trivia

What it actually is

  • Spectral class. Its spectrum reads DA — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.
  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

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 12.2 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Draco.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around June — 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. ≈ 609.5 thousand years at Voyager 1's speed (17 km/s).

About GL GJ 1206

GL GJ 1206 is a rare variable star. It lies about 34.7 light-years from Earth, sits in the constellation Dra, shines at apparent magnitude 12.24 and has spectral type DA.

Its spectrum reads DA — 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 1206 in the constellation Dra. At apparent magnitude 12.24, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 1206 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 1206 is a rare variable star

GL GJ 1206 scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.

That score comes from 6 science badges — Variable star, Never sets (northern circumpolar), White dwarf (a burnt-out core), Intrinsically feeble (Mv > +12), Gently variable and A named variable star — 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.
