CoRoT-4 (formerly known as CoRoT-Exo-4[6]) is a yellow-white dwarf main-sequence star in the constellation Monoceros.[3]

Planetary system[edit]

The star is orbited by one known extrasolar planet, designated CoRoT-4b. It was catalogued as part of the CoRoT mission to find transiting planets, when a planet was spotted using the transit method.[5]
