Space news: Astronomers discover largest solar system known so far


The largest known solar system has been discovered by astronomers one trillion kilometers away.

A report from the Monthly Notices of the Royal Astronomical Society has revealed that a planet called 2MASS J2126-8140 which is 12 to 15 times heavier than the mass of Jupiter exists in another solar system three times larger than the previous star-planet pair discovered.

The gigantic planet takes about a million years to complete its orbit around its star and is 140 times wider than Pluto’s course around the sun.

“We were very surprised to find such a low-mass object so far from its parent star,” said Australian National University’s Dr. Simon Murphy, as reported by BBC. “There is no way it formed in the same way as our solar system did, from a large disc of dust and gas.”

The scientists discovered that the star and its orbiting planet have almost the same distance as the Sun and the Earth. This astronomical discovery was found when the team members were surveying brown dwarfs and young stars around the Earth.

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

According to a Earthsky, there are indeed a number of other stars bigger than the sun. The heaviest star is called the R136a1, which is 265 times the sun’s mass. Also known as the Wolf-Rayet star, the massive gas is located in the Large Magellanic Cloud about 160,000 light years away from earth.

That is too far compared to the distance between the sun and the Earth which is about 100 light years. A light year is a measure of astronomical distance equal to how far light could travel within a year. One light year is equivalent to 9.4607 1 trillion kilometers.
