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

Rossiter–McLaughlin effect
The Rossiter–McLaughlin effect is a spectroscopic phenomenon observed when an object moves across the face of a rotating star. The star is seen to undergo a redshift anomaly caused by the obscuration of different parts of its disk.

HD 209458 b
HD 209458 b is an exoplanet, specifically a hot Jupiter, that orbits the solar analog HD 209458 in the constellation Pegasus, some from the Solar System. The radius of the planet's orbit is , or one-eighth the radius of Mercury's orbit (). Th ...

/ref> 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
CoRoT-3b (formerly known as CoRoT-Exo-3b) is a brown dwarf or massive extrasolar planet with a mass 21.66 times that of Jupiter. The object orbits the stellar classification, F-type star CoRoT-3 in the constellation of Aquila (constellati ...
, 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.[Astronomers Discover Circumbinary Planet 3,700 Light-Years Away](_blank)

/ref> 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.
There are 60 members of multi-planet systems.
