2MASS J22362452+4751425 b

Gas GiantUninhabitable227 light years awayFound 2016

2MASS J22362452+4751425 b, from the NASA Exoplanet Archive (found 2016). Measured: 3970 Earth masses, 230 AU, a 4045 K K-type star. Composition inferred from a mass of 3970 Earths, which is giant territory whatever its 2.13x density suggests, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Gas Giant

Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 86.0% hydrogen and helium, combined with a mass of 3970.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 86.0% (>60% required)✓ Mass: 3970.0x Earth (>10x required)

The TerraForge exoplanet catalog: 5,572 real exoplanets run through the simulation, with a search field and rendered worlds grouped by type

New: The Exoplanet Catalog 🔭

Every confirmed planet NASA has measured well enough to build — 5,572 of them — is now in here, and none of them arrived with a label. Their real mass, radius, orbit and star go through the same simulation that runs everything you make, and it decides what each one is: gas giant, lava world, ocean, ice. Sixteen come out Earth-like. Find TRAPPIST-1e, stand on its surface, and see what a red dwarf's light actually looks like from the ground.
