Kepler-171 and Its Three Planets

Kepler-171 is a star 2820 light-years away with three known planets. The star is 3.47 billion years old, has 1.07 solar masses, 1.09 solar radii, and a temperature of 5950 K.

All three planets were discovered by transit in 2014. Kepler-171 b is a Super-Earth with an orbital period of 4.17 days and a radius of 2.34 Earth radii, larger than Earth's. Kepler-171 c is Neptune-like, with an orbital period of 11.5 days and a radius of 2.56 Earth radii, larger than Earth's. Kepler-171 d is a Super-Earth with an orbital period of 39.6 days and a radius of 1.89 Earth radii.

Among the listed planets, Kepler-171 b has the shortest year, Kepler-171 c the second-shortest, and Kepler-171 d the longest. Kepler-171 c has the largest radius, while Kepler-171 d has the smallest.
