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

Characteristics

[edit]

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

[edit]

In 2011, a group of astronomers working within the CoRoT program announced[1] 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.

CFHTWIR-Oph 98 b is a Super-Jupiter exoplanet that orbits CFHTWIR-Oph 98 A, a M-type star. [1]

Formation

[edit]

It orbits a star but its formation as an exoplanet is challenging or impossible.[2] If it’s formation scenario is known, it may explain the formation of Planet Nine.
