Scientists discover ‘rogue planet’ outside solar system

Scientists discover ‘rogue planet’ outside solar system

It also has a strong magnetic field that is more than 200 times stronger than Jupiter's.

According to the researchers, this object came to be some 200 million years ago and is traveling all alone in the cosmos, with no other star in its proximity to revolve around.

When astronomers are searching the depths of space for new objects it's typically easier to find undiscovered planets if they're orbiting a star.

The odd object, called SIMP J01365663+0933473, has a magnetic field which is more than 200 times stronger than the magnetic field field of Jupiter, according to the study published in The Astrophysical Journal Supplement Series. Its surface seems to be about 825 degrees Celsius, while the Sun's surface reaches the 5,500.

Previously, scientists have determined the exact distance to the North star.

The study's findings have been published in the Astrophysical Journal.

It's believed that the magnetic dynamo mechanisms of this particular space object will help scientists discover more planets beyond our solar system using auroral radio emissions.

Tesla take-private skepticism grows after Elon Musk's funding claim
Musk's money-losing and cash-burning company is an unlikely candidate for debt investors to be willing to help go private. The board, they said, had met "several times" over the last week and was actively working to "evaluate" the proposal.

A brown dwarf is an object too large to be a planet, but isn't big enough to sustain the nuclear fusion of hydrogen in its core that is typical of stars.

This is the first planetary mass object detected with a radio telescope.

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

The planetary-mass object has been classified as rogue meaning it's free-floating and is not hitched to any parent star. This fits with the object being between a planet and a brown dwarf and could provide valuable information about both groups. It is the radio signature of these auroras that allowed the researchers to detect these objects.

Auroras on Earth are created when charged particles from the Sun interact with Earth's magnetic field.

Initially the object was registered in 2016 as one of the brown dwarfs, the study of which is engaged in the VLA. One theory is that auroras happen when a planet or moon interacts with the brown dwarf's magnetic field.

Such a 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", adds Gregg Hallinan, of Caltech, who also worked on the study.
