Solar system could soon have a ‘Planet Nine’

New Delhi: Solar system could soon have a replacement for Pluto, which was robbed of its ‘ninth planet of the solar system’ tag and dubbed as a ‘dwarf star’.

Researchers at the California Institute of Technology have found evidence of a giant planet tracing a highly elongated orbit in the outer solar system.

Nicknamed as ‘Planet Nine’, the celestial body has a mass about 10 times that of Earth and orbits about 20 times farther from the sun on average than does Neptune, which orbits the sun at an average distance of 2.8 billion miles.

The newly discovered planet is so far that it would take it between 10,000 and 20,000 years to make just one full orbit around the sun.

"This would be a real ninth planet. There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our solar system that's still out there to be found, which is pretty exciting,” said researcher Mike Brown, who discovered the planet's existence through mathematical modeling and computer simulations.

Researchers Konstantin Batygin and Mike Brown haven’t actually seen the planet, however, their research helped them to conclude that there is one.

“All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found. Now we can go and find this planet and make the solar system have nine planets once again," he added.
