About this world
Kepler-103 c is a Neptune-like planet orbiting Kepler-103, a yellow, Sun-like star (type G2) 1.61 thousand light-years from Earth. It is about 5.5 times the size of Earth and holds 58 Earth masses. It completes an orbit every 180 days at 0.67 AU from its star.
Its equilibrium temperature is about 434 K (161 °C): far too hot for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2014 by transit with Kepler. A planet crosses its star and dims it by a tiny, periodic fraction. Kepler-103 has 2 known planets; the others are Kepler-103 b.
