So... 400 deg C on the 'surface' and wandering in line with a cluster of stars... I'd put that in the category of a warm "Big Jupiter", perhaps still cooling down from coalescing. I expect there are wandering free bodies such as comets, asteroids and planets, that have been ejected from their home star system. However, I don't see how we can see to find them with our present capabilities... They have no star to illuminate them! Perhaps the SKA has a chance to see cold lost wandering planets at radio frequencies for their cool emissions? Or will they be far too cold and lost in the noise?

Looks like there are wandering nomads out there. First glance I thought they found the (hypothetical planet) Tyche. ____________________________________________________ The universe wastes nothing, it's simply transferred. ID: 1306703 ·

Quite possibly, except there would be many lifetimes and many generations for any inhabitants on a 'base' there before sweeping past any other star systems... Sorry to kill that old TV series dead :-( But yes, there must be many coalesced bodies of all sizes lost wandering alone and dark in the vastness of space. Including star systems except that we can see those.
