Kepler-817 b: A Jupiter-like World in a Close Orbit
Kepler-817 is a star located 4840 light-years away, with an age of 3.55 billion years. Its mass is 1.03 solar masses and its radius is 1.03 solar radii, while its temperature is 5860 K. One planet orbits this host.
That planet is Kepler-817 b, a Jupiter-like world discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-817 b has an orbital period of 3.99 days and a radius of 9.03 Earth radii. Its reported radius estimate is larger than Earth's, and a Jupiter-like planet exceeds 4 times Earth's radius.
