I saw this video, https://youtu.be/LFDhW-IpbJc

And it got me thinking, could tidal heating provide enough heat for an earth like object to have liqued water? If there woupd be live woupd vision be usseles? Or would life adopt a seismic way of seeing (like toph from avatar) and when the rogue planet woupd be ejected is it possible that it could even maintain/snag multiple moons as well?

I am waiting for your input(pic partially unrelated, depends on answers)
