Scientists discovered the largest solar system -made only for a planet and a star separated by a trillion kilometers away-the known Universe, academic sources reported Wednesday.
“We surprised to find a low-mass object (the planet) so far from its parent star” said Simon Murphy School of Astronomy and Astrophysics at the Australian National University.
This academic center has a international team of investigators studying the planet known as 2MASS J2126-8140.
In its work, the team discovered that the planet, which has a mass exceeding twelve times that of Jupiter, orbits a dwarf star named TYC 9486-927-1.
Both bodies are separated by a equivalent to 6,900 astronomical units away, that is, 0.1 light year or 1,000,000,000 000 kilometers, according to a statement from the Australian National University.
That distance is “close to three times larger” than the hitherto regarded as the largest solar system.
If this planet is orbiting in the solar system would be located beyond Pluto , in the middle of the Oort cloud, within the limits of the solar system.
The distance between the duo from the 2MASS makes the TYC J2126-8140 9486-927- 1 looks like a star with moderate brightness in the sky and its light would take a month to reach the planet.
Murphy believes that giant planet has not been formed in the same way that the solar system, ie from a great disc dust and gas.
“We can speculate that (…) gas filament pushed the two together in the same direction” , said Murphy.
The scientist found that planet and star “would not have lived together in a very dense environment. They are so tenuously linked to any nearby star had disturbed its orbit completely, “added the Australian expert.
The research of the new solar system, to be published in the journal Monthly Notices of the Company Royal Astronomical, was led by Niall Deacon of Britain’s University of Hertfordshire and included Joshua Schlieder of Ames Research Center of NASA .
