Kepler-1677 and Its Neptune-Like Planet
Kepler-1677 is a star located 2400 light-years away. It has 1.11 solar masses, 1.25 solar radii, and a temperature of 6010 K, making its reported mass, radius, and temperature estimates larger and hotter than the Sun's. One planet orbits this host.
That planet, Kepler-1677 b, is Neptune-like, a size class that reaches 4 times Earth's radius. Discovered in 2020 by the transit method, in which a planet passing in front of its star dims the observed brightness, it has a radius of 2.7 Earth radii, larger than Earth's. Its orbital period is 22.1 days.
