Kepler-193 and Its Two Known Planets

Kepler-193 is a star located 3290 light-years away, and two planets have been found orbiting it. The host star is 2.88 billion years old, with a mass of 1.14 solar masses, a radius of 1.21 solar radii, and a temperature of 6160 K. Its mass and radius are larger than the Sun's, and its temperature is hotter.

Both planets were discovered by transit in 2014, the method in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Kepler-193 b is a Super-Earth with an orbital period of 11.4 days and a radius of 2.39 Earth radii. Kepler-193 c is Neptune-like, with an orbital period of 50.7 days and a radius of 2.75 Earth radii. Both planets' radii are larger than Earth's.

Among the listed planets, Kepler-193 b has the shortest year, while Kepler-193 c has the longest. Kepler-193 b also has the smallest radius, and Kepler-193 c has the largest.
