New Discovered Planet Doesn’t Orbit a Star

New Discovered Planet Doesn’t Orbit a Star

The rogue body is almost large enough to be considered a gas giant planet and it offers researchers the opportunity to study these massive objects, shedding light on their magnetic realities. It appears to be traveling through space alone. It was initially thought to be much larger and much older, but the new study has found that the object (called SIMP J01365663+0933473) is "only" 200 million years old.

"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, an astronomer at Arizona State University.

The Karl G. Jansky Very Large Array radio telescope has detected emissions, presumably from an aurora, generated by an unusual body 12 times more massive than Jupiter and generating a magnetic field 200 times more intense that is flying through space on its own 20 light years from Earth. Scientists aren't exactly sure how the auroras form in brown dwarfs, but they do have some theories. This is at least how astronomers believed planets worked till they stumbled upon the first ever "rogue planet" that has been simply set adrift in the Milky Way.

The planetary-mass object has been classified as rogue meaning it's free-floating and is not hitched to any parent star. The auroras are similar to those on Earth that happen when our magnetic field interacts with solar wind. Astronomers agree that the difference can be drawn as the line below which deuterium fusion is no more possible, known as the "deuterium-burning limit", it stands at around 13 Jupiter masses. They have detected a possible "rogue" planetary-mass object. However, a nearby moon or another orbiting planet may be the answer.


The newly identified planet was originally detected in 2016 in New Mexico, but was considered at that time to be a brown dwarf. New analysis has proved that it is in fact a proper planet with an extraordinarily powerful magnetic field.

The rogue planet's strong aurora is being compared to the northern lights and aurora borealis seen on Earth.

She continued: "We think these mechanisms can work not only in brown dwarfs, but also in both gas giant and terrestrial planets".

The odd "rogue" planet rotates around the galactic center in interstellar space.
