Kepler-93 and Its Two Worlds
Kepler-93 is a star 313 light-years away with two planets orbiting it. The host star is 6.6 billion years old, holds 0.911 solar masses and 0.919 solar radii, and has a temperature of 5670 K. Its reported mass estimate is smaller than the Sun's, its reported radius estimate is smaller than the Sun's, and its reported temperature is cooler than the Sun's.
Kepler-93 b is an Earth-like planet found by the transit method in 2014, when a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. It has a mass of 4.66 Earth masses, a radius of 1.48 Earth radii, and an orbital period of 4.73 days. Its reported radius estimate is larger than Earth's, and its reported mass estimate is also larger than Earth's. Its mean density is 7.95 g/cm³, 1.44 times Earth's.
Kepler-93 c was discovered in 2014 using the radial velocity method, which measures the wobble a planet's gravity induces in its star's motion. Its mass is a reported lower limit of 954 Earth masses, and its orbital period is a reported lower limit of 1460 days.
