Kepler-36b is an exoplanet orbiting the star Kepler-36. This planet has the closest conjunction to Kepler-36c every 97 days. Its density is similar to that of iron.During their closest approach Kepler-36b and Kepler-36c are located only 0.013 AU (less than 2000000 km) from each other which causes extreme transit-timing variations for both planets. Transit-timing variations caused by Kepler-36c are strong enough to put narrow constraints on Kepler-36b’s mass.
