About this world
EPIC 201754305 d is an Earth-sized planet orbiting K2-16, an orange dwarf (type K3V) 1.09 thousand light-years from Earth. It is about 1 times the size of Earth. It completes an orbit every 2.72 days at 0.033 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 982 K (709 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2019 by transit with K2. A planet crosses its star and dims it by a tiny, periodic fraction. K2-16 has 3 known planets; the others are K2-16 b and K2-16 c.
