Lonely Planet in the Largest Orbit Ever Noticed by Astronomers
A team of astronomers in the UK, U.S. and Australia has revealed that the planet, which they thought to be lonely till now, is not actually lonely. The planet, known as 2MASS J2126, is actually in the largest ever found orbit around its parent star that is located 1 trillion kilometers away from it. The planet’s orbit is 7,000 times wider than the orbit of Earth around the sun and will take nearly 900,000 years to complete its one orbit. The ‘Monthly Notices of the Royal Astronomical Society’ published the outcomes of the team.
"This is the widest planet system found so far and both the members of it have been known for eight years, but nobody had made the link between the objects before”, said the lead author of the study, Dr. Niall Deacon of the University of Hertfordshire.
He added the planet is not as lonesome as thought to be. In fact it is in a very long distance relationship with its parent star. Both the planet and its star are 104 light years from Earth and were discovered eight years ago by U.S. researchers. The discovery was made during an infrared sky survey, thereby making it possible for the researchers to categorize 2MASS J2126 as a young planet with relatively less mass.
It was later found by the researchers from Canada that 2MASS J2126 is likely to be a part of a group of stars and brown dwarfs, which is 45 million years old, named as the Tucana Horologium Association. These findings helped the astronomers in determining that the planet’s mass will be approximately 12-15 times more than the mass of Jupiter. According to Simon Murphy of Australian National University, the creation and endurance of such a huge planetary system is still unknown to humankind.
