i believe they're classified as 'erratic wandering planets'.

are you asking/suggesting if a wanderer could sustain life, and as such be a mobile base of sorts?

the problem with a hot core is that a planet needs to be close to a sun's gravitational influence to maintain it's heat (i think, i might be wrong), if a planet escapes, or is blown out of, it's system then the core would rapidly (relatively speaking) cool which would, in essence, turn it into a colossal asteroid with a giant ball-bearing in the middle.
