The discovery of the world’s largest solar system (so far) – Ecuavisa

The last discovered by astronomers solar system is also the largest known to date.

And in it is a lonely planet to turn around its sun needs almost a million years ( terrestrial).

It consists of a huge planet with an orbit that is 140 times wider than Pluto’s around the sun.

In recent years there have been a bunch of these couples with star and planet orbits extremely wide.

But this gas giant is a lonely one billion kilometers from the star, the equivalent of 7,000 times the distance between Earth and the sun.

The planet, known as 2MASS J2126-8140, is 12 to 15 times the mass of Jupiter. That is, between 3,816 and 4,770 the mass of Earth.

The distance between the star and the planet is such that if you stop at this mass of gas alone would see the sun as a bright star.

However, despite its size, is considered small by the experts regarding the extent of its orbit.

“We were very surprised a low mass object is as far from its star, “said Dr Simon Murphy of Australia National University (ANU for its acronym in English).

” No way has been formed in the same way that our Solar System, a large disk of dust and gas. “

Inventory

This planetary system is almost three times the size the former partner of planet and star discovered.

This star, known as TYC 9486-927-1, and your planet were found during a survey of young brown dwarf stars.

Not all are so crowded solar systems like our own.

The studio head Niall Deacon, University of Hertfordshire, carried the last years of his career studying stars young companions in wide orbits.

As part of its work, the leadership team reviewed a list of known young stars, brown dwarfs and planets floating freely to see if any of them were related.

Once the team found that both the star and the planet were at a similar distance from Earth about 100 years -a light- compared the movement both in space and realized they moved together.

“This is the system of wider planet found so far, and for eight years was aware of both,” she said Deacon to the Royal Astronomical Sociaty, where the study was published. “But no one had made the link between the two objects.”

“The planet is not as lonely as previously thought, but definitely is in a long distance relationship.”

If an individual lived on the planet would see her as a distant sun shining star and perhaps not even imagine that is connected to your world.

Meanwhile, Murphy said, “We can speculate that this couple was formed about 10 million to 45 million years ago, from a gas filament pushed in the same direction”.

Taking account the distance of the planet to its star, the planet Experts estimate that it takes about 900,000 Earth years to reverse. Which means what life brings complete this journey less than 50 times.

To get an idea, the Royal Astronomic Society explains that if an individual lived on the planet only see his sun like a distant shining star, and perhaps not even imagine that is connected to your world.
