The new discovered planet does not evolve around any sun, so it just wonder through space without exposing to Gravaity. The planet size is huge as it reaches more than four times of Jupiter. The astronomers that discovered the planet gave it a code name CFBDSIR2149.
Astronomers have long theorised about the possibility of free-floating planets that are not trapped by the gravitational attraction of a nearby star but this is the first time they have been able to confirm one’s existence.
Detailed calculations carried by at team of Canadian and French scientists show that the planet is comparatively young, between 50 and 120 million years old, with a surface temperature of 400C. This, combined with its size, rules out the possibility of it being a larger “brown dwarf” star, astronomers said.
A joint investigation between astronomers working on the Canada-France-Hawaii Telescope and the Very Large Telescope in Chile operated by the European Southern Observatory led to an accurate estimate of the planet’s age, a key fact that ruled out the possibility of it being a brown dwarf.
The free-floating planet appears to be part of larger grouping of about 30 young stars, all with a similar composition, that are moving through space together. This helped the scientists to pinpoint the planet’s age.
