An artist's interpretation which shows the free-floating planet CFBDSIR2149, at 100 light years away |
This planet was observed at the Canada-France-Hawaii Telescope located in Mauna Kea in Hawaii. They were searching for 'brown dwarfs' but this was unsuccessful.
This planet is approx 4-7 times the size of Jupiter. It was discovered by the infrared glow that is emitted from its core.
Based on their research, the astronomers believe with a high probability that this is a young, free-roaming planet rather than a brown dwarf. It is moving with a group of stars.
Required background information:
1. Size of Jupiter- Equatorial diameter is 143,000 km. Jupiter's mass is 318 times that of Earth's.
2. Rogue planet- Free-floating, nomad planet, orphan planet (not gravitationally bound to any stars or brown dwarf.
3. Brown dwarf- Brown dwarfs are objects which have a size between that of a giant planet like Jupiter and that of a small star.
****This discovery definitely gives scientists and astronomers world wide another angle to discover and further study is essential.
There is real potential in further astronomy study.
