But over a long enough time period...
Long before then, if the Sol system is left untouched by humans or other technological beings, Sol will be a black dwarf, most of the inner planets will be long fried, and I wonder if the outer worlds will have drifted away into deep space?
We only have a couple billion years left before Sol starts expanding into first an orange then a red giant star, frying everything on Earth - but ironically starting the processes for life on Titan that are currently frozen. Europans and Enceladusians might take advantage of the turned up celestial thermostat too.
