TOI-2093 b
Ice GiantUninhabitable270 light years awayFound 2025
TOI-2093 b, from the NASA Exoplanet Archive (found 2025). Measured: 10.6 Earth masses, 0.097 AU, a 4426 K K-type star. Composition inferred from a measured bulk density of 0.31x Earth's — too light for bare rock, so a large fraction of water and ice, with a day locked to its 12.8-day year, as anything orbiting this close would be.

Ice Giant
Magnetic FieldExtreme Activity
Why is this a Ice Giant?Your planet has moderate mass (10.6x 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: 10.6x Earth (5-20x range)✓ Water/Carbon/Nitrogen rich composition
Habitability ScoreUninhabitable
Contributing Factors
temperature5
Scorching - hot enough to melt lead, though rock stays solid; no chance for life
atmosphere18
Hydrogen-rich atmosphere typical of gas giants (partially stripped by slow rotation)
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
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides
