Original Note:
NNN. K-2 18b is ~8.6x the mass of earth with a radius ~2.6x and a surface area ~6.8x earth’s. Unless otherwise clearly specified, it’s generally understood that apparent size (diameter, radius, and circumference) is what’s meant by “size.” All 3 of these are ~2.6x earth’s. https://en.wikipedia.org/wiki/K2-18b https://www.nasa.gov/universe/exoplanets/webb-discovers-methane-carbon-dioxide-in-atmosphere-of-k2-18-b/
