K2-3c also known as EPIC 201367065 c is an exoplanet orbiting K2-3 a red dwarf, every 24 days 137 ly away.[1][2] It has a density of 1.82g/cm3 indicating that it could be a Gas dwarf or a Mini-Neptune, it is one of the smallest gas planets ever discovered. Despite not being the smallest planet in the system by radius,[3] by mass it is by far the least massive with a mass only double of that of Earth.[3]
