[Red Dwarf] Do we know what state Earth is in after Lister wakes up?

Obviously the universe is now populated by GELF and Simulants, but what has become of Earth and Mankind?

Nothing on screen, but the last novel says there was a trash crisis and the governments held a Sol-wide vote on where it should all be dumped. Earthicans couldn't be arsed to go to the polls, so Earth lost and was designated the system land-fill.

Some time later an errant pilot was trying to write his name in dumped waste and crashed, igniting an enormous gas pocket from one of the trash-continents, pushing it out of orbit. Earth literally farted its way out of the Solar system and became a rogue planet travelling the Milky Way.
