KPS-1 and Its Jupiter-Like Planet

KPS-1 is a K1 V star, a main-sequence dwarf, located 857 light-years away. Its reported mass estimate is 0.892 solar masses and its reported radius estimate is 0.907 solar radii, both smaller than the Sun's. With a reported temperature of 5170 K, it is cooler than the Sun. One planet is known to orbit this star.

That planet, KPS-1 b, is a Jupiter-like world, a size class that exceeds 4 times Earth's radius. Its reported radius estimate is 11.5 Earth radii, larger than Earth's, and its reported mass estimate is 346 Earth masses, also larger than Earth's and roughly 1.09 times Jupiter's mass. Its mean density is 1.24 g/cm³, 0.225 times Earth's.

KPS-1 b was discovered 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. It completes its orbit in 1.71 days.
