Kepler-577 and Its Neptune-Like Planet
Kepler-577 is a star 1710 light-years away with one known planet in orbit. The host star is 3.8 billion years old and has a mass of 0.78 solar masses, a radius of 0.73 solar radii, and a temperature of 4980 K. Its mass and radius are smaller than the Sun's, and its temperature is cooler.
The single planet, Kepler-577 b, was discovered by transit in 2016. A transit occurs when a planet passes in front of its star from our viewpoint, producing a small dip in brightness that can repeat to reveal an orbital period. Kepler-577 b completes an orbit every 25.7 days. Its radius is 2.55 Earth radii, larger than Earth's. That radius places it among the Neptune-like planets, whose size class reaches four times Earth's radius.
