Kepler-102
Kepler-102 is a star in the constellation of Lyra. It has five known exoplanets. Kepler-102 is less luminous than the Sun.On January 2014, a system of five planets around the star was announced, three of them being smaller than Earth. While 3 of the transit signals were discovered during the first year of the Kepler mission, their small size made them hard to confirm as possibilities of these being false positives were needed to be removed. Later, two other signals were detected. Follow-up radial velocity data helped to determine the mass of the largest planet.
