But seriously, the idea of this being Nibiru would be exciting, but there isn't enough information.

Just because matter is whitin gravitatin influence of he black hole doesn't mean it's inside the black hold you clearly can't read English because I stated several times it's matter from the accretion disk accelerated to fast from the black holes gravity that it never enters the black hole. You seem like you didn't even read my post lol.
Oh and if you think you know so much about space I'd like to remind you our galaxy is actually 100,000 acres this was confirmed years ago if you know so much more why are you posting info that's been proven wrong ages ago. Get real

No, the black hole doesn't encompass the accretion disk. While a black hole may be accompanied by an accretion disk, it is not necessarily so. And likewise, we also find accretion disks around normal stars, and they may even form around planets. The extent of a black hole is defined by the Schwarzschild radius. One can say matter or light has entered the black hole when it is at a distance from the singularity equal to or less than the Schwarzschild radius. That boundary is the event horizon.

A Black Hole consists of the singularity AND the accretion disk. Matter is in the accretion disk it is considered to be in the black hole - why? Because for the matter to be in the accretion disk in the first place it must be within the gravitational influence of the black hole. Seeing as a black hole is simply a point of infinite gravity and density, the accretion disk is therefore part of it.
1) Objects with true masses below the limiting mass for thermonuclear fusion of deuterium (currently calculated to be 13 Jupiter masses for objects of solar metallicity) that orbit stars or stellar remnants are "planets" (no matter how they formed). The minimum mass/size required for an extrasolar object to be considered a planet should be the same as that used in our Solar System.
2) Substellar objects with true masses above the limiting mass for thermonuclear fusion of deuterium are "brown dwarfs", no matter how they formed nor where they are located.
3) Free-floating objects in young star clusters with masses below the limiting mass for thermonuclear fusion of deuterium are not "planets", but are "sub-brown dwarfs" (or whatever name is most appropriate).
