Gigantic Rogue Planet Found Lurking Outside Our Solar System

Gigantic Rogue Planet Found Lurking Outside Our Solar System

Astronomers have detected a possible "rogue" planetary-mass object with a surprisingly powerful magnetic field travelling through space unaccompanied by any parent star.

The new discovery, made with the National Science Foundation's Karl G. Jansky Very Large Array telescopes in New Mexico, marks the first radio observations of a planetary-mass object beyond our solar system.

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

It's thought that SIMP J01365663+0933473 is only 200 million years-old and is just 20 light-years away from Earth. For comparison, the Sun has a surface temperature of 5,500 degrees Celsius or nearly 10,000 degrees Fahrenheit. It is 12 times bigger than Jupiter and has a very odd feature: it does not orbit any star.

Brown dwarfs have long baffled experts because they're too big to be considered planets but are not big enough to be stars.

SIMP is not small; and is about 12 times larger than Jupiter and has a strong magnetic field, say the astronomers.

Brown dwarfs were predicted to exist all the way in the 1960s, but the first one was only discovered in 1995, confirming the initial theories.

Astronomers have discovered a rogue planet that's nearly too big to be considered a planet - and to top it off, the rogue object is a magnetic powerhouse.

Astronomers originally came to the conclusion that the object was a brown dwarf because of its mass and because it does not revolve around a star like a planet typically does.

It is these radio signatures emitted by the auroras of such rogue objects that allow researchers to detect them.

The Caltech team that originally detected its radio emission in 2016 had observed it again in a new study at even higher radio frequencies and confirmed that its magnetic field was even stronger than what they had measured the first time.

The auroras on our planet are caused by its magnetic field interacting with the solar wind (the continuous flow of charged particles from the sun's upper atmosphere, known as the corona, that permeates the solar system). Scientists theorise that one possibility is having a planet or moon interact with the dwarf's magnetic field.

The unusually strong magnetic field "presents huge challenges to our understanding of the dynamo mechanism that produces the magnetic fields in brown dwarfs and exoplanets and helps drive the auroras we see", said Caltech's Gregg Hallinan.

The difference between what constitutes gas giants and brown dwarfs is a matter of serious debate among astronomers, says NRAO.
