data

CoRoT-6 is a magnitude 13.9 star located in the Ophiuchus constellation.[6]

Location and properties

The star has a radius of about 102% of the Sun and a mass of about 110% of the Sun.[2] It is a main sequence F type star a little larger and hotter than the Sun.

Planetary system

The star is orbited by one known extrasolar planet identified as CoRoT-6b. The discovery was made by the CoRoT program using the transit method.[2]
