Astronomers using the National Science Foundation's Karl G. Jansky Very Large Array (VLA) have made the first radio-telescope detection of a planetary-mass object beyond our Solar System. The object, about a dozen times more massive than Jupiter, is a surprisingly strong magnetic powerhouse and a "rogue," traveling through space unaccompanied by any parent star.
"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.
The strange object in the latest study, called SIMP J01365663+0933473, has a magnetic field more than 200 times stronger than Jupiter's. The object was originally detected in 2016 as one of five brown dwarfs the scientists studied with the VLA to gain new knowledge about magnetic fields and the mechanisms by which some of the coolest such objects can produce strong radio emission. Brown dwarf masses are notoriously difficult to measure, and at the time, the object was thought to be an old and much more massive brown dwarf.
Last year, an independent team of scientists discovered that SIMP J01365663+0933473 was part of a very young group of stars. Its young age meant that it was in fact so much less massive that it could be a free-floating planet -- only 12.7 times more massive than Jupiter, with a radius 1.22 times that of Jupiter. At 200 million years old and 20 light-years from Earth, the object has a surface temperature of about 825 degrees Celsius, or more than 1500 degrees Farenheit. By comparison, the Sun's surface temperature is about 5,500 degrees Celsius

Let's name this object "Paladin."
Am I to believe that this giant planet is just passing through the neighborhood near the solar system, or it is in some sort of orbit? If it is just sort of near is it moving farther away or getting closer?
With built-in inertialess braking, it will be here in 20 years. You’ll know when it joins the massive invasion fleet in the Ort Cloud and begins to send real rods-from-G_D your way ... or maybe just amp up their fields and compress the entire solar system. Tough choices, I’m sure.
We're gonna need a bigger speaker.
Then we'll just amp up loud enough to shatter said rods with the dulcet-questionable rendition of Slim Whitman's "Indian Love Call".
Or just use the Alaskan HARP.
None of those will reach the Ort Cloud where the attack will come from.
But if you need rally big speakers and a group to play the noise, then I suggest Disaster Area the loudest band in the Galaxy and the loudest noised of any sort.
“The Hitch Hikers Guide to the Galaxy notes that Disaster Area, a plutonium rock band from the Gagrakacka Mind Zones, are generally held to be not only the loudest rock band in the Galaxy, but in fact the loudest noise of any kind at all.
“Regular concert-goers judge that the best sound balance is usually to be heard from within large concrete bunkers some thirty-seven miles from the stage, whilst the musicians themselves play their instruments by remote control from within a heavily insulated spaceship which stays in orbit around the planet - or more frequently around a completely different planet.”
Made a note to myself to not wear my watch when I explore it.

Likely there are ten to a hundred planet sized bodies for every star in the Milky Way. A lot would be free-range and harder to spot. This one sings in the radio spectrum and caught attention.
How myths and fantasy are born.
