comment Time Contraction
After some more reading it appears that the stay-at-home twin could be seen to be changing reference frames as the Earth accelerates and decelerates during its journey around the Sun. Perhaps the problem with my question above is the misuse of terminology or the angle from which I am approaching the question. Perhaps I should rather start by asking if someone stationary on Earth will age slower than someone stationary on Pluto?

Thanks, I'll take a look at those references.

So, if the surface of Earth where the stay-at-home twin lives is moving at a certain speed, then I am asking how would the time dilation equation be interpreted if the space travelling twin were to remain stationary in the space ship relative to the Sun, thus in a 'slower' frame of reference relative to the stay-at-home twin? The Earth would continue rotating and travelling around the Sun, thus travelling at a velocity greater than that of the spaceship.

Thank you once again. That does make a lot of sense. My next question is then what if the space travelling twin were to change reference frames to an inertial frame slower than than that of the stay at home twin?

Thank you for the clarification. As I said, I'm no physicist, I just came across this stuff the other day and had some thoughts. The text book I was looking at said that in the twin paradox the younger twin jumped forward in time. Would this not be relative to the older twin? If so, could you not state that the older twin jumped backwards in time relative to the younger twin?

You need to use -(v^2) instead of (-v)^2. The reason for this is that practically, you can't have time dilation occurring from both inertial frame perspectives, otherwise you would never have the twin paradox.
