Kepler1649

Kepler-1649 is an exoplanet orbiting the red dwarf star Kepler-1649, located about 300 light-years away in the constellation Cygnus. It was discovered by NASA's Kepler Space Telescope.

The planet is particularly noteworthy because it is the most Earth-like planet found by the Kepler mission to date. Kepler-1649c, its designation, is similar in size to Earth, being only 1.06 times larger in radius. It orbits within the habitable zone of its star, the region where liquid water could potentially exist on the planet's surface. This means Kepler-1649c receives about 75% of the light energy that Earth receives from the Sun.

Kepler-1649c completes an orbit around its star every 19.5 Earth days. The star itself is cooler and dimmer than our Sun, which is why the planet can be within the habitable zone at such a close orbital distance.

While Kepler-1649c is considered a promising candidate for habitability, it is important to note that its atmosphere and composition are currently unknown. Further observations and research are needed to determine if it truly possesses the conditions necessary for life. The Kepler-1649 system also hosts another planet, Kepler-1649b, which is closer to its star and likely too hot to be habitable.
