Re: An Earth-size planet is careening untethered through the galaxy,

What Sci-Fi books have involved a planet that is free
and unteathered to any sun / star?

Robert Heinlein kind of mentioned one, in "Have Space Suit —
Will Travel" he has an unpleasant species of aliens
hauled before an "intergalactic tribunal, composed of many advanced 
species which have banded together for self-protection and
the -the Wormfaces are put on trial first. -- and are judged to
be dangerous. Their planet is "rotated" out of three-dimensional
space without their star.
