Trivia

What makes it special

  • Ultra-hot Jupiter. So hot that iron vaporises and rains back down as molten metal.
  • Heavyweight. Packed denser than solid iron.

By the numbers

  • Size. About 11.9× the width of Earth.
  • Volume. About 1685 Earths could fit inside it.
  • Mass. Roughly 8899× Earth's mass — about 28 Jupiters.
  • Your weight. You'd weigh about 62.8× your Earth weight standing here.
  • Density. Denser than solid iron.
  • Temperature. Around 2677 K — hot enough to vaporise iron.

How we found it

  • Discovery. Found by European Space Agency (ESA) Gaia Satellite using the imaging method.

Why 2MASS J11011926-7732383 b is an anomaly exoplanet

2MASS J11011926-7732383 b scores 79 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 16 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Hot Jupiter, Ultra-hot Jupiter, Denser than iron and Directly imaged — 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.
