•Astronomers discover new planet in Great Bear constellation
87% Informative
Astronomers from the Nicolaus Copernicus University in Torun have discovered a new planet in the Great Bear .
It has a mass as much as 11 times that of Jupiter , and orbits its star in 14 years .
The star's physical parameters are similar to those of the sun, and it is 20 percent more massive and twice as large as the sun.
The discovery was made with the first of the world's first astrographs, the Draper telescope.
Astronomers discover a hierarchical planetary system around HD 118203 .
One planet forms a tight pair with its star, and a second planet orbits the pair in an orbit wide enough to form another pair with the first one.
Both planets are massive and orbit in rather elongated orbits.
Despite this, their mutual gravitational influence does not destabilize the system on a scale of millions of years .
