Trivia

What it actually is

  • What it is made of. Too light to be solid rock and too heavy to be all gas: most likely a deep global ocean or a thick steamy envelope over a rocky core.

Find it in the sky

  • 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 May — that's when to go looking.

Standing on it

  • Two suns. Two suns would rise and set in its sky — a real-life Tatooine.

By the numbers

  • Size. About 13.3× the width of Earth.
  • Your weight. You'd weigh about 4.5× your Earth weight standing here.
  • Mass. Roughly 795× Earth's mass — about 2.5 Jupiters.
  • Volume. About 2353 Earths could fit inside it.

Why PSR B1620-26 b is an uncommon exoplanet

PSR B1620-26 b scores 23 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 11 points would lift it into a rarer tier.

That score comes from 3 science badges — Confirmed exoplanet, Gas giant and Circumbinary (orbits both stars) — 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.
