A planet takes 900,000 years to orbit its star, with the two objects separated by a distance almost 7,000 times that between Earth and the Sun.

Niall Deacon at the University of Hertfordshire in Hatfield, UK, and his colleagues found that the previously known star and the planet — located about 32 parsecs (104 light years) from Earth — move across the sky at the same speed and in the same direction, which suggests that the two form a pair.

The star, TYC 9486-927-1, is young, at just a few tens of millions of years old. And the planet has a mass between 12 and 15 times that of Jupiter — which makes it big and bright enough to be spotted from Earth through a telescope, unlike most other exoplanets.
