Changes in planet orbits as a star (eg. the Sun) decreases is mass.

Yes planets are moving their orbits as sun losses mass. But numbers are almost insignificant. When you add both solar winds and mass-energy conversion of sun, I think that you get about one earth's own radius increase in earth's orbit over entire life of sun so far.

Thanks for the answer. Sorry if it sounded like a stupid question, I didn't realise that the change in Orbit would be so insignificant.
