That would be the case with most brown dwarfs but Y class stars could be the exception as they are considered the coolest dwarf class. Some so cold, they emit no visible light at all. Suggesting there could be others out there so cold, they emit little to no infrared as well. Considering they're so difficult to spot due to their temp., we don't fully understand them yet. A decade out, even an object of this size, could be extremely difficult to spot.

I considered this and assume it won't start to glow until it get's closer to the sun, just as comets do. Yes, that is within Jupiter's orbit usually but that may be when this star starts to glow red. Either due to it's natural color, added heat by the sun, or both. We simply don't understand Y class dwarfs enough to dismiss them as objects we could easily spot. Amongst many other factors in my research, this was one of the key reasons I speculated it might be a Y class dwarf.

You could also be correct in that it is not a dwarf at all but some other deep orbital body. This is seemingly more plausible but my research continues to put my instincts on a Y class dwarf. I would not mind being wrong about any of this.
