Star temperature and orbital distance set incoming energy, but stellar size is also required. This calculation uses a typical radius for the listed spectral type, 30% reflectivity and even heat redistribution. It is not a ground-temperature forecast: air, clouds, oceans and surface reflectivity could move the result by tens to hundreds of degrees.

The marker above the bar is a typical temperature for this star’s class. The line below is Earth’s Sun.

orange-gold

Kepler-62 is class K2 V. Its daylight would have a warmer orange-gold cast than sunlight on Earth.

Representative daytime geometry only; the star’s height in the sky changes through the day.

[ GROUND.TXT ]STILL INFERENCE

Most plausible case. The colder Kepler-62 world. Same orange K2 star, now from 0.72 AU, so the star spans about 0.48°, almost exactly the Sun’s size in Earth’s sky, and the planet receives about half of Earth’s light. Radius 1.41 Earth radii. A 267-day year, so the star should rise and set. Cool ground, frost more plausible than on planet e, rock if the greenhouse is modest. The huge archive mass is an upper limit.

Dry case. Cold rock and dust under a Sun-sized orange star. Not a hot desert.

Thick-air case. CO₂ greenhouse and cloud, the usual outer-habitable-zone sketch. Unseen.

Walking. About 78% heavier than Earth in the model, near 1.8 g. Planet e is a tiny disk. The daylight is orange and half of Earth’s energy, with a star that looks about as wide as ours.

Based on: Borucki et al. 2013; S 0.50, Rp 1.41, a 0.718 AU. Mass is an upper limit. Page gravity 1.78 g is modelled.

Positions, distances, and system parameters come from the NASA Exoplanet Archive composite table, queried 25 Sep 2026. GJ 273 b uses the parallax in that row, 12.4 light-years. The 45 worlds follow Bohl, Lawrence, Lowry, and Kaltenegger.
