“Kepler-1649c was discovered by reanalyzing archival data from NASA's Kepler space telescope, which was retired in 2018. The planet had been missed because an automated computer algorithm initially misidentified it as a false positive; a team of scientists re-examining the flagged signals recovered it as a genuine planet. The discovery was published in 2020 as a habitable-zone Earth-sized planet rescued from false-positive status,…”

“Kepler-1649c is only about 1.06 times the radius of Earth, making it among the closest in size to Earth of any Kepler planet, and it receives about 75 percent of the amount of light Earth receives from the Sun, implying its temperature may be similar to Earth's if it has a comparable atmosphere. It orbits its small red dwarf host so closely that a year on Kepler-1649c lasts only about 19.5 Earth days, yet because the star is dim and…”
Earth-Size, Habitable Zone Planet Found Hidden in Early NASA Kepler Data · Size, insolation, and orbit
“Kepler-1649 is a red dwarf, the most common type of star in the galaxy, which means Earth-size habitable-zone planets like Kepler-1649c could be more common than previously thought. However, red dwarfs are known for stellar flare-ups that may make a planet's environment challenging for any potential life by delivering bursts of high-energy radiation and driving atmospheric loss. Although no flares were observed in this particular…”
