Kepler-642 and Its Neptune-Like Planet
Kepler-642 is a star 2550 light-years away with one known planet. The host star is 1.95 billion years old, has a mass of 1.4 solar masses and a radius of 1.66 solar radii, and has a temperature of 6570 K. Its reported mass estimate is larger than the Sun's, its reported radius estimate is larger than the Sun's, and its reported temperature is hotter than the Sun's.
The planet Kepler-642 b is Neptune-like. It was discovered by transit in 2016, and repeated dips in the star's brightness helped establish its orbital period of 4.42 days. Kepler-642 b has a radius of 2.9 Earth radii, which is larger than Earth's. A Neptune-like planet reaches 4 times Earth's radius.
