A study released Monday revealed a second planet orbiting Beta Pictoris, a young star in our own galaxy.
"We are talking about a huge planet that is about 3,000 times as massive as Earth and 2.7 times as far from its star as Earth is from the Sun," said Anne-Marie Lagrange, astronomer at the National Center for Scientific Research in France, principal author of a study in Nature Astronomy .
The new planet β Pictoris c completes its orbit approximately every 1
Beta Pictoris is a newborn to the naked eye – with a mass nearly twice that of the Sun – and only 23 million years old.
The sun is more than 4.5 billion years old.
It is also relatively close, just over 63 light-years, and surrounded by a stellar dust disk.
This whirling halo of rubble and gas was the first such configuration captured in the image, making Beta Pictoris a star in the 1980s.
The best planetary system we know, "Lagrange told AFP.
Observations show that the two planets are still taking shape.
β Pictoris c was discovered by analyzing 10-year high-resolution data obtained from La Silla Observatory in northern Chile, operated by the interstate European Southern Observatory.
According to scientists, β Pictoris b 2014 revolves at a furious speed of about 25 kilometers per second.
Located in the southern constellation Pictor – "The Painter & # 39; s Easel" – Beta Pictoris is the second brightest star in its constellation.
