Rogue planet

A planet that does not orbit a host star has been found 100 light years from Earth.
The planet, named CFBDSIR2149, is known as a rogue or free-floating planet because it wanders through space free of its parent star.


This planet has a temperature of around 398 degrees Celsius it also has a mass between four and seven times bigger than Jupiter's.


A rogue planet is thought to form in two different ways  it either starts as a normal planet and is then kicked out its star system believed to be the case with CFBDSIR2149 or it begins the same way a star does  from collapsing gas and dust  but does not have enough mass to cause the nuclear fusion that creates starlight.
