PDS 70 c

PDS 70 c, from the NASA Exoplanet Archive (found 2019). Measured: 2380 Earth masses, 34.3 AU, a 4109 K K-type star. Composition inferred from a mass of 2380 Earths, which is giant territory whatever its 0.22x density suggests, with an assumed 24-hour day — rotation cannot be measured for exoplanets. Note: TerraForge comes out at 37 K against the archive's 1054 K, because that figure is the planet's own heat, not the star's. It receives almost no sunlight out at this distance and is still glowing from its formation — TerraForge only warms worlds with starlight, so it has no way to model a planet heated from within.
