CoRoT-20

CoRoT-20 is a star, which is located in the constellation Monoceros at a distance of about 4011 light years from the Earth. The star is orbited by at least two planets.

Characteristics

CoRoT-20 is a very young star of 14.66 magnitude by astronomical standards. Its age is estimated at approximately 100 million years. In terms of mass and radius, it is almost identical to the Sun. Its surface temperature is about 5880 kelvins. CoRoT-20 got its name thanks to the space telescope CoRoT, which discovered its two planets.

Planetary system

In 2011, a group of astronomers working within the CoRoT program announced the discovery of the planet CoRoT-20b and CoRoT-20c in this system. It is a hot gas giant, more than four times the mass of Jupiter. However, the planet's radius is only 84% of Jupiter's, which indicates an average high density. CoRoT-20b and c both orbit close to its parent star - at a distance of 0.09 AU The discovery of the planet was made by transit method.
