Trivia

Hard to believe

  • True brightness. It pours out about 147.2 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 DA — a white dwarf — the exposed, Earth-sized cinder of a dead star, with nothing left to burn.

Find it in the sky

  • How to spot it. At magnitude 11.9 you'll want a small backyard telescope, over in Lynx.
  • 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 January — that's when to go looking.

Its true colour

  • Its true colour. Measured through blue and visual filters it comes out brilliant white (B−V 0) — hotter and whiter than the Sun, the colour of Sirius or Vega.
  • Why no green stars. No star ever looks green: a surface hot enough to peak in green also floods out plenty of red and blue, and your eye blends the mixture back to white.

By the numbers

  • Surface temperature. Its colour puts the surface at roughly 9880 K, against the Sun's 5778 K.

Why GL GJ 3435 is an uncommon star

GL GJ 3435 scores 25 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 9 points would lift it into a rarer tier.

That score comes from 2 science badges — Star and White dwarf (a burnt-out core) — 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.
