CoRoT-8 is a star in the constellation Aquila at a distance of about 1239 light-years. It hosts at least one planet.
CoRoT-8 is an orange dwarf with a mass of 0.88 solar masses and a radius of 0.77 solar radii.[3] 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 which its planetary companion was discovered.
In 2010, 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 0.0636 AU from the parent star, while making a complete revolution in 6.212445 days.[4][5][6]
