}} By astronomical standards, this is already a rather young star compared to the Sun: its age is about 3 billion years. It got its name in honor of the CoRoT space telescope, with the help of which its planetary companion was discovered.

In 2010, a group of astronomers working within the CoRoT program announced the discovery of the planet CoRoT-8b in this system. It is a hot gas giant, similar in mass and size to Saturn. The planet orbits at a distance of about 0.06 AU from the parent star, while making a complete revolution in 6.21 days.
