Trivia

What it actually is

  • Spectral class. Its spectrum reads G5IV — a G-type star: the very same spectral class as our own Sun.
  • Where it is in life. It is a subgiant, caught in the act of leaving the main sequence as the hydrogen in its core runs out.

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 5.8 you can see it with your own eyes from a dark site, over in Phoenix.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • 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. ≈ 868.8 thousand years at Voyager 1's speed (17 km/s).

Its spectrum reads G5IV — a G-type star: the very same spectral class as our own Sun.

How to see it

Look for GL GJ 1021 in the constellation Phe. At apparent magnitude 5.8, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, GL GJ 1021 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 1021 is an uncommon star

GL GJ 1021 scores 24 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 10 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Naked-eye visible, Sun-like G-type star and Subgiant (leaving the main sequence) — 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.
