Floating Exoplanet Has Extremely Strong Magnetic Field | Astronomy

Brown dwarf or massive exoplanet detected with powerful magnetic field

Gigantic Rogue Planet Found Lurking Outside Our Solar System

The planet is only around 20 light years from Earth, but it's not really doing much besides relaxing in the vastness of space. The planet is skirting the boundaries of our solar system - just 20 light years from Earth - and may prove to be an invaluable source of astronomic knowledge.

"'This object is right at the boundary between a planet and a brown dwarf, or 'failed star, ' and is giving us some surprises that can potentially help us understand magnetic processes on both stars and planets", said Dr. Melodie Kao, who led the study while a grad student at Caltech, on National Radio Astronomy Observatory website.

According to experts, it is common for similar observations to be made on brown dwarfs, aborted stars with high mass to be considered as planets, but without enough to trigger nuclear fusion reactions and become stars. As reported by Naked science, the mass of an object exceeds the mass of Jupiter is 12 times, he has a very powerful magnetic field.

Apparently, outside our solar system astronomers came up across a giant planet, 12 times bigger than Jupiter.

Though not as hot as our Sun, this newly discovered object is quite toasty at about 1,500 degree Fahrenheit.

It was once thought that no such object could exist and the first failed star was not discovered until 1995. And according to a recently published study in The Astrophysical Journal, this odd, nomadic world has an incredibly powerful magnetic field that is some 4 million times stronger than Earth's. It is estimated that the field is over 200 times stronger than the one present on Jupiter. That's an incredible finding, and it suggests that there's some very interesting things going on above the planet's surface. "We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets".

An unaccompanied brown dwarf like SIMP JO1365663+0933473, the object detected by the VLA, does not have a companion star and thus is not flying through a solar wind. It's an absolutely massive alien world that is almost big enough to be classified as a brown dwarf. On Earth, colorful auroras are produced from the interaction of its magnetic field and solar wind.

Though it was first detected in 2016, scientists initially identified it as one of five recently discovered brown dwarfs.
