TOI-1080 b

Gas GiantUninhabitable83 light years awayFound 2026

TOI-1080 b, from the NASA Exoplanet Archive (found 2026). Measured: 10.7 Earth masses, 0.0272 AU, a 3065 K M-type star. Composition inferred from a measured bulk density of 6.19x Earth's, far too high for silicates alone — an iron-rich world, with a day locked to its 4.0-day year, as anything orbiting this close would be.

Gas Giant

Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 0.0% hydrogen and helium, combined with a mass of 10.7x 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: 0.0% (>60% required)✓ Mass: 10.7x 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.
