Trivia

What it actually is

  • Spectral class. Its spectrum reads dM4.5-5 — 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 on the main sequence, quietly fusing hydrogen in its core exactly as the Sun does.

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 15.5 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Ophiuchus.
  • Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
  • Best time of year. It stands highest in the middle of the night around May — 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. ≈ 948.9 thousand years at Voyager 1's speed (17 km/s).

About GL GJ 3937

GL GJ 3937 is an uncommon star. It lies about 54 light-years from Earth, sits in the constellation Oph, shines at apparent magnitude 15.51 and has spectral type dM4.5-5.

Its spectrum reads dM4.5-5 — 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 3937 in the constellation Oph. At apparent magnitude 15.51, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, GL GJ 3937 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 3937 is an uncommon star

GL GJ 3937 scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.

That score comes from 5 science badges — Star, Cool red M-type star, Deep red star, Red dwarf 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.
