Kepler-36b is an exoplanet orbiting the star Kepler-36.[1] 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 (about 1,900,000 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.
