Day and nightLikely synchronous spinProbably spins once per orbit, keeping one hemisphere in permanent day and the other in permanent night. Heuristic: likely at ≤0.25 AU, uncertain to 0.50 AU, probably not beyond; rotation is not directly measured.

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. A likely synchronous spin also means the permanent day and night sides would not share one ground temperature.

[ STARLIGHT.SPC ]VISIBLE LIGHT ONLY

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

red-orange

Kepler-1652 is class M2V. Its visible daylight would be dim and strongly red-orange; most of its energy is infrared.

Representative lit-side geometry only. On a locked world, the star’s real elevation would depend on where you stand.

[ GROUND.TXT ]STILL INFERENCE

Most plausible case. A 1.60-Earth-radius planet receiving about 81% of Earth’s light. The star, 0.38 solar radii and 3638 K, spans about 1.2°. Orange-red daylight, a bit under Earth’s energy. Rock with night-side ice if the surface is solid. At 1.6 radii a water-rich layer is also a standard reading, and the mass is not measured.

Dry case. Cool-to-temperate rock and dust. Not an inner-edge bake, and not an outer-edge ice ball.

Thick-air case. A volatile envelope is plausible at this radius and would hide the ground under cloud.

Walking. About 25% heavier than Earth, modelled. No known sibling planet is listed in the archive composite used here. The star is magnitude 17, about 820 light-years away.

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.
