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-442b

Kepler-442b is an exoplanet orbiting a cooler star approximately 1,200 light-years from Earth. Its size and position within its star’s habitable zone make it notable for potential liquid water on its surface. Scientists study this super-Earth to understand the diversity of planets capable of supporting life outside our solar system. The planet's high Earth Similarity Index is particularly relevant...
