Trivia

What makes it special

  • Lava world. Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.

Hard to believe

  • It would float. It is less dense than water. Drop it in a big enough ocean and the whole world would bob on the surface.

What it actually is

  • What it is made of. Lighter than Neptune — a puffed-up ball of hydrogen and helium with no surface anywhere on it to stand on.

Find it in the sky

  • 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 December — that's when to go looking.

By the numbers

  • Size. About 87.2× the width of Earth.
  • Temperature. Around 2100 K — hot enough to vaporise iron.
  • Your weight. You'd weigh about 0.8× your Earth weight standing here.

About V2376 Ori b

V2376 Ori b is an epic exoplanet. It has spectral type M, has an equilibrium temperature near 2,100 K, spans roughly 87.21 Earth radii and weighs about 6,356.57 Earth masses.

Its surface is almost certainly an ocean of molten rock, kept liquid by the star it hugs.

How to see it

Like any astronomical target, V2376 Ori b 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 V2376 Ori b is an epic exoplanet

V2376 Ori b scores 63 points on Spacedle's rarity scale, which places it in the epic tier. Another 15 points would lift it into a rarer tier.

That score comes from 6 science badges — Confirmed exoplanet, Gas giant, Lava world, Puffy low-density world, Directly imaged and Orbits beyond Neptune's distance — 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.
