Astronomers have found the largest known solar system at a distance of one trillion kilometers. A report released from the Monthly Notices of the Royal Astronomical Society has disclosed that a planet known as 2MASS J2126-8140, which is 12 to 15 times heavier as compared to the mass of Jupiter, is present in another solar system. It is three times bigger than the last star-planet pair discovered.

The gigantic planet completes its orbit around its star in nearly a million years. It is 140 times wider in comparison to Pluto's course around the sun.

BBC reported that Australian National University's Dr. Simon Murphy said that they were quite astonished to discover such a low-mass object at such a huge distance from its parent star. Dr. Murphy said that there isn’t any way that its formation has taken place in the same way as that of our solar system’s, from a huge disc of dust and gas.

The scientists have noted that the distance between the star and its orbiting planet is nearly the same distance as the Sun and the Earth. They made this astronomical discovery when the team members were studying brown dwarfs and young stars around our planet.

Dr. Murphy continued, “We can speculate they formed 10 million to 45 million years ago from gas filament that pushed them together in same direction. They mustn’t have lived in very dense environment, and are tenuously bound together that any nearby star would have disrupted their orbit completely”.

As per Earthsky, there are actually numerous other stars larger than the sun. The heaviest star is known as the R136a1, which has 265 times the mass of the sun. Also called the Wolf-Rayet star, the enormous gas is present in Large Magellanic Cloud, nearly 160,000 light years away from Earth.
