TOI-2267 b

Rocky TerrestrialExtremely Harsh74 light years awayFound 2025

TOI-2267 b, from the NASA Exoplanet Archive (found 2025). Measured: 0.972 Earth masses, 0.0205 AU, a 3030 K M-type star. Composition inferred from a measured bulk density of 0.97x Earth's, which is rock and iron, with a day locked to its 2.3-day year, as anything orbiting this close would be.

Rocky Terrestrial

Magnetic FieldModerate Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (25.0%) and iron (12.5%) content, forming a rocky terrestrial body.
Rocky terrestrial planets are primarily composed of silicate rocks and metals. They're the most common type of small planet in the universe.
Classification Criteria:
✓ Silicon: 25.0% + Iron: 12.5% + Magnesium: 3.8%✓ Mass: 1.0x Earth (terrestrial range)

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.
