K2-7 and Its Jupiter-Like Planet
K2-7 is a star located 2410 light-years away, and it hosts one known planet. The star is 8.6 billion years old and has a mass of 1.06 solar masses, a radius of 1.53 solar radii, and a temperature of 5700 K. Its radius estimate is larger than the Sun's.
The planet K2-7 b was discovered by transit in 2015, when it passed in front of its star from our viewpoint and caused a small dip in observed brightness. It is classified as Jupiter-like, a size class for planets whose radius exceeds 4 times Earth's. K2-7 b's radius estimate is 4.04 Earth radii, larger than Earth's, and its orbital period is 28.7 days.
