That's why I proposed a black or brown dwarf

Blacm dwarves give off virtually no radiation, and the only way to detect it would be by gravitonal influence. Black Dwarves have yet to be observed because the universe isn't old enough for white dwarves to cool completely and extinguish. But since this is made up RP we might fudge that.

Brown dwarves give off little signature, and are among the coldest stars, so cold that many act more like planets than stars in their own right. Something like that, with less than ten Jovian masses, almost 47 billion miles away, might have what gravitational effect it has slip by observations.
