Trivia

What makes it special

  • Not one star but two. It is a binary: two stars orbiting a shared centre of mass. More than half of all the 'stars' you can see are actually multiple systems.

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 14.4 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Antlia.
  • 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 February — 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. ≈ 1.1 million years at Voyager 1's speed (17 km/s).
  • Fastest probe ever. ≈ 101.9 thousand years even at the Parker Solar Probe's 192 km/s.

About GL GJ 1130B

GL GJ 1130B is an uncommon star. It lies about 65.2 light-years from Earth, sits in the constellation Ant and shines at apparent magnitude 14.42.

It is a binary: two stars orbiting a shared centre of mass. More than half of all the 'stars' you can see are actually multiple systems.

How to see it

Look for GL GJ 1130B in the constellation Ant. At apparent magnitude 14.42, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 1130B 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 1130B is an uncommon star

GL GJ 1130B scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.

That score comes from 4 science badges — Star, Binary star, 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.
