New Planet Discovered

Scientists have discovered a new planet.Ho hum. This has become so common-place, it isn't typically reported anymore. What makes this one newsworthy? ... It doesn't bother to have a parent sun.That's right, it's just wandering around in space, about 80 light-years from us, with no sun, and no other symptoms of a 'planetary system'. In early science fiction, such a planet might be called a 'rogue planet'.Since this rogue is not orbiting a star, they didn't find it in the usual way, either. The usual way, these days, is to observe the changes in the star's brightness to determine when a planet's orbit places it between that star and Earth.The way they discovered this planet was by looking for Brown Dwarf stars. Brown Dwarf stars, as I understand it, are 'larger than a planet, but not warm enough to have ignited into a star.' While searching for large, cool masses, they discovered this rogue, which was even colder than the brown dwarfs they were looking for.At this point, they don't know much about it; only that it doesn't orbit a star, it's about 12 million years old, and it's about 6 times the mass of Jupiter.I wonder if it could be considered a tiny brown dwarf? When I was (much) younger, I seem to remember wild speculation that Jupiter was just a little too small to have been a 2nd sun in this system, and in 2010 (as I remember the movie) aliens added enough mass to Jupiter to get it to ignite into another sun.
Well, for now, it's a planet. Of course, its status could change. Pluto was once a planet, too. After all, it's not as if astronomy is an exactscience.
