It is part of a system that also contains a debris disk and at least four massive planets.

With a mass at least 15.2 times that of Jupiter, it may be a massive planet or a small brown dwarf.

The closer they got, the bigger the moon seemed, until it was a full planet, massive and variegated.

The more massive the planet, and greater the gravitational tug on the host star.

The identity of this object as a brown dwarf or a massive planet was thus unclear.

In 2007 a massive extrasolar planet was reported orbiting the star.

It is one of the most massive planets ever discovered.

Such object could likely turn out a brown dwarf or even a massive jovian planet.

They would pass that massive planet at the safe distance of a full hundred million miles.

It easily finds massive planets that are close to stars.
