An incredible discovery took place in astronomy. For the first time, “stargazers” discovered planetary system, which orbits the planet around the central star for nearly a million years. This system has become the largest of the planets known to date.
Exoplanet – a gas giant named 2MASS J2126-8140, has a mass of 12-15 Jupiter. Planet removed from the brightness of the 1 trillion km, or 140 times the distance between Pluto and the sun.
The diameter of the planetary system is almost three times greater than the diameter found earlier counterparts, reports BBC.
It is found in the program of observations of young stars and brown dwarfs (protoplanets) in the immediate galactic environment sun. Astronomers did not immediately realize that they are watching are not two independent object at the same distance from the Sun – about 100 light years, and the planetary system.
“We were very surprised by the discovery of an object with a relatively small weight so far from the central star,” – said Dr. Simon Murphy, of the Australian National University. – Unlike solar, the system could not have arisen from a huge dust cloud “.
According to him, the system is formed of 10-45 billion years ago from a gas stream, which was moving in the same direction.
