Kepler-93b (KOI-69b) is a hot, dense transiting Super-Earth exoplanet located approximately 313 light-years (96 parsecs)[4] away in the constellation of Lyra,[5][6] orbiting the G-type star[5] Kepler-93. Its discovery was announced in February 2014 by American astronomer Geoffrey Marcy and his team.[1] In July 2014, its radius was determined with a mere 1.3% margin of error, the most precise measurement ever made for an exoplanet's radius at the time.[7]
