Trivia

What it actually is

  • Spectral class. Its spectrum reads DC9+ — 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 17.8 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 April — 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. ≈ 1.4 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 126.7 thousand years even at the Parker Solar Probe's 192 km/s.

How to see it

Look for GL GJ 3754 in the constellation UMa. At apparent magnitude 17.82, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 3754 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 3754 is a rare star

GL GJ 3754 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 5 science badges — Star, Never sets (northern circumpolar), White dwarf (a burnt-out core), Deep red star 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.
