CoRoT-20 explained

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.^[1] In terms of mass and radius, it is almost identical to our 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.
