Kepler-595 c

Rocky TerrestrialUninhabitable2096 light years awayFound 2020

Kepler-595 c, from the NASA Exoplanet Archive (found 2020). Measured: 3.3 Earth masses, 0.0983 AU, a 5139 K K-type star. Composition inferred from a measured bulk density of 3.20x Earth's, far too high for silicates alone — an iron-rich world, with a day locked to its 12.4-day year, as anything orbiting this close would be.

Rocky Terrestrial

High Activity
Why is this a Rocky Terrestrial?Your planet is dominated by silicate (36.6%) and iron (24.4%) 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: 36.6% + Iron: 24.4% + Magnesium: 12.2%✓ Mass: 3.3x Earth (terrestrial range)

Contributing Factors
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life
atmosphere6
No atmosphere - exposed to radiation and temperature extremes (partially stripped by slow rotation)
water0
No water - the recipe has no hydrogen and oxygen to form it
magnetic Field30
No magnetic field - vulnerable to solar radiation
geology90
Active geology recycles nutrients and drives carbon cycle
Organic Chemistry20
Limited organic chemistry potential
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides

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.
