CoRoT-8 is a star in the constellation Aquila at a distance of about 1239 light-years from us. At least one planet revolves around a star.
Characteristics
CoRoT-8 is an orange dwarf which has 0.88 solar masses and 0.77 solar radius. [1]. 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 her planetary companion was discovered.
Planetary system
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. e. from the parent star, while making a complete revolution in 6.21 days.
