Kepler1649b

Kepler-1649b is an exoplanet orbiting the red dwarf star Kepler-1649, located approximately 300 light-years away from Earth. It was discovered by NASA's Kepler Space Telescope and its existence was announced in 2020. The planet is roughly 1.06 times the size of Earth, placing it in the category of potentially rocky, Earth-sized worlds.

What makes Kepler-1649b particularly noteworthy is its location within the habitable zone of its star. This means that the planet receives an amount of stellar energy that could allow liquid water to exist on its surface, a key ingredient for life as we know it. The planet's orbit is about 19.5 Earth days long.

While Kepler-1649b is considered to be in the habitable zone, there are still many unknowns about its atmosphere and actual surface conditions. Its star, Kepler-1649, is much cooler and dimmer than our Sun. The planet is also tidally locked, meaning one side perpetually faces its star, which could lead to extreme temperature differences. Despite these uncertainties, Kepler-1649b remains a significant discovery in the search for exoplanets that might harbor life.
