Multicolor image from the Pan-STARRS1 telescope of the free-floating planet PSO J318.5-22, in the constellation of Capricornus. The planet is extremely cold and faint, about 100 billion times fainter in optical light than the planet Venus. Most of its energy is emitted at infrared wavelengths. The image is 125 arcseconds on a side. Credit: N. Metcalfe & Pan-STARRS 1 Science Consortium

"I had often wondered if such solitary objects exist, and now we know they do." Well now that you know, what are you going to do about it?

I’m guessing there are a lot of them out there.

How much bigger would it need to be to ignite? Then it would just be another young star.

Yet another cosmic body that will stretch the definition of planet as decreed by the IAU. Why not give this group of objects another name, using Latin this time out. Say, Vagus, or my favorite, Peregrinus?

“has a mass only six times that of Jupiter.”
ONLY?
To: Red Badger
Fromm what I remember from college wouldn’t the size of the planet be very close to the critical mass needed for the formation of a star?

Sounds like a young, large protoplanet that got flung, for some reason, from one of the young stars in the vicinity.
Maybe gravity hasn't had enough time to increase its' density or rotational speed is too great?

Six times Jupiter's mass is more like a failed star than a planet (which I think by definition should be orbiting
something). One more thing for Red Dwarf and the boys to accidentally run into.

...has a mass only six times that of Jupiter.A failed star, insufficient mass to start the reaction, or coalescing and reaction to start soon- maybe a few million more years.
