description Overview

K2-3 d

K2-3 d is a transiting exoplanet orbiting K2-3, a nearby cool M-dwarf star. It was identified from observations by NASA’s K2 mission and has a radius in the super-Earth range, larger than Earth but smaller than Neptune. Its orbital period is about 45 days, placing it near the region where temperatures may permit liquid water under suitable atmospheric conditions, although the planet’s actual atmos...

Kepler-438b

Kepler-438b is a near-Earth-sized exoplanet confirmed by NASA in 2015, orbiting within the habitable zone of a red dwarf star located approximately 472 light-years away. It has a radius only 12 percent larger than Earth's, making it one of the most Earth-like planets discovered in terms of physical size and stellar irradiation. However, subsequent observations of its host star revealed frequent an...
