K2-295 b
Gas GiantUninhabitable760 light years awayFound 2018
K2-295 b, from the NASA Exoplanet Archive (found 2018). Measured: 106 Earth masses, 0.0451 AU, a 4444 K K-type star. Composition inferred from a mass of 106 Earths, which is giant territory whatever its 0.10x density suggests, with a day locked to its 4.0-day year, as anything orbiting this close would be.

Gas Giant
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 86.0% hydrogen and helium, combined with a mass of 106.0x Earth, which exceeds the gas giant threshold.
Gas giants form when massive cores capture enormous atmospheres of light gases. They typically form beyond the 'frost line' where volatiles can condense.
Classification Criteria:
✓ Hydrogen + Helium: 86.0% (>60% required)✓ Mass: 106.0x Earth (>10x required)

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
rotation65
Slow rotation - significant day/night temperature variations, but life can adapt
