TOI-3568 b
Gas GiantUninhabitable645 light years awayFound 2024
TOI-3568 b, from the NASA Exoplanet Archive (found 2024). Measured: 26.4 Earth masses, 0.0485 AU, a 4969 K K-type star. Composition inferred from a measured bulk density of 0.18x Earth's, which only hydrogen and helium can explain, with a day locked to its 4.4-day year, as anything orbiting this close would be. Note: TerraForge comes out at 1527 K against the archive's 899 K, because it models stars by spectral class, and TOI-3568 is not an average K-type.

Gas Giant
Magnetic FieldExtreme Activity
Why is this a Gas Giant?Your planet has 86.0% hydrogen and helium, combined with a mass of 26.4x 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: 26.4x Earth (>10x required)

Hydrogen-rich atmosphere typical of gas giants
water15
No solid surface — any water is locked in a supercritical mantle and hot ice, not oceans

Organic Chemistry80
Core organic elements (CHNO) present
rotation30
Very slow rotation - extreme temperature swings between eternal day and night sides
