Trivia

Hard to believe

  • True brightness. It pours out about 586.1 thousand times as much light as the Sun. It only looks ordinary because it is so far away.

What it actually is

  • Spectral class. Its spectrum reads K0 — a K-type star. Orange K dwarfs are the marathon runners of the galaxy, burning steadily for tens of billions of years.

Find it in the sky

  • How to spot it. At magnitude 10.4 you'll want a small backyard telescope, over in Sculptor.
  • 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.

Its true colour

  • Its true colour. Measured through blue and visual filters it comes out orange (B−V 1.1) — cooler than the Sun, and the kind of star that burns steadily for tens of billions of years.

By the numbers

  • Surface temperature. Its colour puts the surface at roughly 4550 K, against the Sun's 5778 K.

What's in a name

  • Its catalogue. A Gliese number marks it as part of the census of the Sun's own neighbourhood — the catalogue of stars near enough to be our neighbours.

Why GL GJ 2015 is a trash star

GL GJ 2015 scores 6 points on Spacedle's rarity scale, which places it in the trash tier. Another 9 points would lift it into a rarer tier.

That score comes from 2 science badges — Star and Orange K-type star — 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.
