Trivia

What it actually is

  • Spectral class. Its spectrum reads M4.5Ve — 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.
  • It changes. This star does not hold still: its brightness rises and falls on a rhythm of hours, days or years, either pulsing in size or being eclipsed by a companion.

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 11.2 you'll want a small backyard telescope, over in Canis Minor.
  • 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 January — that's when to go looking.

Could we get there?

  • Verdict. Hopelessly far for any craft humanity can build today.

About GL Gl 285

GL Gl 285 is an epic variable star. It lies about 19.4 light-years from Earth, sits in the constellation CMi, shines at apparent magnitude 11.19 and has spectral type M4.5Ve.

Its spectrum reads M4.5Ve — 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 Gl 285 in the constellation CMi. At apparent magnitude 11.19, a small backyard telescope will bring it into view.

Like any astronomical target, GL Gl 285 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 Gl 285 is an epic variable star

GL Gl 285 scores 51 points on Spacedle's rarity scale, which places it in the epic tier. Another 27 points would lift it into a rarer tier.

That score comes from 9 science badges — Variable star, Nearby (<25 ly), Cool red M-type star, Main-sequence star, Deep red star, Red dwarf, Intrinsically feeble (Mv > +12) and Gently variable — 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.
