TOI-411 b
Gas GiantUninhabitable205 light years awayFound 2022
TOI-411 b, from the NASA Exoplanet Archive (found 2022). Measured: 13.7 Earth masses, 0.0573 AU, a 6169 K F-type star. Composition inferred from a measured bulk density of 5.45x Earth's, far too high for silicates alone — an iron-rich world, 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 0.0% hydrogen and helium, combined with a mass of 13.7x 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: 0.0% (>60% required)✓ Mass: 13.7x Earth (>10x required)

water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans

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