Kepler-1410 b is a planet about 1.8 times Earth's width orbiting an orange dwarf star about 1,200 light-years away. It crosses in front of its star every 60.9 days and receives about as much light as Earth gets from the Sun, 1.06 times as much in a 2017 analysis.
NASA's Kepler space telescope listed it as candidate KOI-3010.01. In 2016 a team led by Timothy Morton validated it as one of 1,284 planets confirmed at once by an automated method that weighs each signal against false alarms such as background eclipsing stars. In 2017 a team led by Guillermo Torres examined it again with a different method, BLENDER, along with spectra and high-resolution images of the star, and validated it with about 99.95 percent confidence.
Those images revealed a complication. A fainter star sits about a third of an arcsecond from Kepler-1410, too close for Kepler to separate. A transit gives a planet's size only in proportion to the star it crosses, so if the planet orbited the fainter companion it would be much larger than it appears. Torres's team allowed for that possibility when estimating the chance that each planet is both small and in the habitable zone. Kepler-1410 b was not among the seven they rated most likely to be both. They estimated its equilibrium temperature, set by starlight alone, at about 290 kelvin. Its mass has not been measured.
