Trivia

What it actually is

  • Spectral class. Its spectrum reads DA9 — 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 15.8 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Ursa Major.
  • 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 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. ≈ 1.2 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 103.1 thousand years even at the Parker Solar Probe's 192 km/s.

About GL GJ 3710

GL GJ 3710 is a rare star. It lies about 66 light-years from Earth, sits in the constellation UMa, shines at apparent magnitude 15.79 and has spectral type DA9.

Its spectrum reads DA9 — 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 3710 in the constellation UMa. At apparent magnitude 15.79, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 3710 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 3710 is a rare star

GL GJ 3710 scores 35 points on Spacedle's rarity scale, which places it in the rare tier. Another 15 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Never sets (northern circumpolar), 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.
