Gigantic Rogue Planet Found Lurking Outside Our Solar System

Hoverer, the new object generates a magnetic field 200 times a powerful as Jupiter's.

Though not as hot as our Sun, this newly discovered object is quite toasty at about 1,500 degree Fahrenheit. By comparison, the Sun's surface temperature is about 9,900 degrees Fahrenheit.

The exact nature of this object remains to be determined.

Astronomers using NSF's Karl G. Jansky Very Large Array have detected a "rogue" planetary-mass object with a surprisingly powerful magnetic field. That's an incredible finding, and it suggests that there's some very interesting things going on above the planet's surface. At the time, researchers thought SIMP was a brown dwarf: an object that's too big to be a planet, but too small to be a star.

The unusual object was discovered in 2016 and originally believed to be a very old brown dwarf.

"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 Melodie Kao, who led this study while a graduate student at Caltech, and is now a Hubble Postdoctoral Fellow at Arizona State University.

A celestial object almost twelve times larger than Jupiter was found floating in space about twenty light-years from Earth.

Though this makes brown dwarfs really puzzling, the team believes further observation of this object could provide more insight into the formation of auroras.

A further study carried out previous year revealed that SIMP was part of a young group of stars.

In fact, scientists are still debating the difference between giant planets and brown dwarfs because of the only distinction they can categorize them based on is size.

At the same time, the team from Caltech, which originally registered the radio emission in 2016, I watched it again during the new study, at much higher RF frequencies, and confirmed that the magnetic field of the object was even stronger than originally thought. It is the radio signature of these auroras that allowed the researchers to detect these objects. The auroras are similar to those on Earth that happen when our magnetic field interacts with solar wind. However, brown dwarfs are typically solitary and don't have a nearby star - therefore they don't have any solar wind to interact with.
