List of transiting exoplanets

This is a list of transiting extrasolar planets sorted by orbital periods. As of 2024, 4195 transiting exoplanets have been discovered. This list consist of all transiting exoplanets through 2012, and notable discoveries since. All the transiting planets have true masses, radii and most have known inclinations. Radius is determined by how much the star dims during the transit and inclination is determined from Rossiter–McLaughlin effect. True mass is determined by the minimum mass determined from radial velocity observations divided by the sine of inclination.

The first known planet to be discovered with the transit method was OGLE-TR-56b. The first planetary transit observed (by already known exoplanet) was caused by HD 209458 b. The most massive transiting exoplanet is KELT-1b which masses 27.23 (making it a brown dwarf) while the least massive is Kepler-42d which masses less than 0.003  or 0.9. The largest exoplanet known is HAT-P-32b which is 2.037. The smallest exoplanet known is also Kepler-42d which is 0.051 or 0.57. The densest transiting exoplanet known is CoRoT-3b, which has density of 26.4 g/cm3; the diffusest transiting planet known is Kepler-12b, which has density of only 0.111 g/cm3. Previously, the longest period of any transiting planets was Kepler-1647b, which takes 1107 days to orbit its (double) stars. Only two years later, the longest period of a transiting planet was more than tripled by EPIC 248847494 b, which takes 3650 days to orbit its star. The shortest period is K2-137b, which takes just 0.18 days to orbit its star.
