Extreme TNOs discovered by ALMA?

A new submm source within a few arcseconds of α Centauri: ALMA discovers the most distant object of the solar system

The serendipitous discovery of a possible new solar system object with ALMA
http://arxiv.org/abs/1512.02650

It could be a 1.5 Earth-radius object 300 AU away, or an extreme TNO pretty far away. Can't be a brown dwarf or WISE would have seen it. Can't be a stellar object or it would have been obvious for a century.

Imho. some healthy skepticism here wouldn't be a bad idea.

Some very negative reactions to these already. Even the TNO idea is questionable.
