"Kao and her team are surprised that the object isn't orbiting a star, a typical behavior of planets.

“Detecting SIMP J01365663+0933473 with the VLA through its auroral radio emission also means that we may have a new way of detecting exoplanets, including the elusive rogue ones not orbiting a parent star,” Caltech's Gregg Hallinan added in the statement.

Originally discovered in 2016, it was only recently that it was identified as a planetary-mass object, having originally been classified as a brown dwarf. Once more data was obtained, the idea that SIMP J01365663+0933473 was a brown dwarf was scrapped.

It's thought that SIMP J01365663+0933473  is only 200 million years-old and is just 20 light-years away from Earth. It also has a surface temperature of 1,500 degrees Fahrenheit, compared to minus 234 degrees Fahrenheit for Jupiter and 10,000 degrees Fahrenheit for the Sun.

It was first detected using a radio telescope, the  National Science Foundation's Karl G. Jansky Very Large Array."
