group of scientists discovered the largest solar system -made only for a planet and a star separated by a million million kilometers away-the known universe, academic sources reported today.
“We were surprised to find an object of low mass (the planet) so far from its parent star,” said Simon Murphy to the School of Astronomy and Astrophysics at the Australian National University .
This academic center has an international team of researchers 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, orbiting a dwarf star called TYC 9486-927-1.
Both bodies are separated by a distance of 6.900 astronomical units, ie 0.1 light year or 1,000,000,000,000 kilometers, according to a statement from the Australian National University.
That distance is “about three times larger” than the so far considered 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 separates the duo from the 2MASS makes the TYC 9486-927-1 J2126-8140 look like a star with moderate brightness in the sky and its light would take a month to reach the planet.
Murphy believes that planet Giant has not been formed in the same way that the solar system, that is, from a large disk of dust and gas.
“We can speculate that (…) the gas filament pushed the two together in the same direction, “said Murphy.
The scientific view that the 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, “he added the Australian expert.
The research of the new solar system, to be published in the journal Monthly Notices of the Royal Astronomical Society, was Niall Deacon led by the British University of Hertfordshire and included Joshua Schlieder Ames Research Center of NASA.
