Is WISE 1828+2650 habitable at all?

I just found out recently, via a temperature of the universe info graphic, that WISE 1828+2650 has a surface temp of 80F/27C.

Is there a maintainable orbit where the radiant temp would be appropriate for human living conditions? What about the surface directly? Other than lack of oxygen, is there anything inherently toxic about the environment that would need to be overcome?

So a few points about this:

- That infographic just gave a single temperature of 27 °C / 80 °F, which is a little disingenuous since it says nothing about the uncertainty. Estimates are that the cloud-top temperature is anywhere between -23 to 127 °C, or -10 to 260 °F.

- Even if the cloud-top temperature really is mild by human standards...that's at cloud-top. There is no surface to stand on, just an atmosphere that gets thicker and thicker, until the pressure and temperature is so great that hydrogen becomes a liquid metal. If this object formed like a brown dwarf, there's likely not even a solid core under all that crushing pressure of metallic hydrogen.

- The range on the mass estimate is pretty large - plausibly anywhere from 3 to 6 Jupiter-masses. That means the gravity at cloud-top is anywhere from about 8x - 15x Earth's gravity. Even if you could float in a balloon at cloud-top, the gravity would crush you pretty quickly - no one can survive that for any extended period, and you'd black-out pretty quickly from your heart being unable to properly pump your blood.

So...don't plan on building your vacation home at WISE 1828+2650 just yet.
