Kepler-1055 and Its Earth-like Planet
Kepler-1055 is a star located 1270 light-years away, and it hosts one known planet. The star is 3.09 billion years old, has a mass of 0.98 solar masses, a radius of 0.94 solar radii, and a temperature of 5720 K. Its reported radius estimate is smaller than the Sun's.
The planet Kepler-1055 b was discovered in 2016 by the transit method, in which a planet passes in front of its star from our viewpoint and causes a small dip in observed brightness. Repeated dips help establish orbital periods. Kepler-1055 b completes an orbit every 2.3 days. It is classified as Earth-like, meaning its radius stays within 1.5 times Earth's radius, and its radius is 1.23 Earth radii, larger than Earth's.
