Trivia

What it actually is

  • Spectral class. Its spectrum reads sdM1 — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.
  • Where it is in life. It is a subdwarf: an old, metal-poor star from the galaxy's early days, a little smaller and fainter than a main-sequence star of the same colour.

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 13.3 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Cepheus.
  • 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 August — 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).

About GL GJ 9722

GL GJ 9722 is an uncommon star. It lies about 78.2 light-years from Earth, sits in the constellation Cep, shines at apparent magnitude 13.3 and has spectral type sdM1.

Its spectrum reads sdM1 — an M-type red star — and M stars are the silent majority: roughly three of every four stars in the galaxy are one.

How to see it

Look for GL GJ 9722 in the constellation Cep. At apparent magnitude 13.3, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 9722 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 9722 is an uncommon star

GL GJ 9722 scores 26 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 8 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Never sets (northern circumpolar), Cool red M-type star, Deep red star and Red dwarf — 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.
