Kepler-24 e

Ice GiantUninhabitable3782 light years awayFound 2014

Kepler-24 e, from the NASA Exoplanet Archive (found 2014). Measured: 26.2 Earth masses, 0.138 AU, a 5897 K G-type star. Composition inferred from a measured bulk density of 1.22x Earth's, which is rock and iron, with an assumed 24-hour day — rotation cannot be measured for exoplanets.

Ice Giant

Magnetic FieldExtreme Activity
Why is this a Ice Giant?Your planet has moderate mass (26.2x Earth) with significant water, carbon, and nitrogen content, characteristic of ice giants.
Ice giants like Uranus and Neptune have icy interiors with thick atmospheres of hydrogen and helium, but not enough to be classified as gas giants.
Classification Criteria:
✓ Mass: 26.2x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition

Contributing Factors
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life
atmosphere30
Hydrogen-rich atmosphere typical of gas giants
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans
magnetic Field100
Magnetic field provides radiation protection
geology40
Extreme volcanic activity may be hazardous
Organic Chemistry80
Core organic elements (CHNO) present
rotation100
Optimal rotation period - balanced day/night cycle, moderate weather, and good heat distribution

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.
