Kepler-87c
Kepler-87c is a planet orbiting Kepler-87, a star slightly more massive than the Sun and nearing the end of its main-sequence period. [1]
Characteristics
Despite being larger than Neptune, Kepler-87c is only about 6.4 times more massive than Earth. This means that its density is only 0.152 g/cm3. This is the first planet with a comparable mass to have such a low density. Its equilibrium temperature is 130 °C.[2]
