HIP 116454 b
Ice GiantUninhabitable203 light years awayFound 2014
HIP 116454 b, from the NASA Exoplanet Archive (found 2014). Measured: 9.7 Earth masses, 0.0792 AU, a 5048 K K-type star. Composition inferred from a measured bulk density of 0.64x Earth's — too light for bare rock, so a large fraction of water and ice, with a day locked to its 9.1-day year, as anything orbiting this close would be.

Ice Giant
Extreme Activity
Why is this a Ice Giant?Your planet has moderate mass (9.7x 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: 9.7x 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 Field30
No magnetic field - vulnerable to solar radiation
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
