Thanks Janus, I'll start looking up some astrophysics texts when I next get the chance and learn all about perturbations. I should probably also mention I incorrectly said Mars takes twice as long to orbit the sun as the Earth, when in fact the reverse is true.
Thanks for all the responses. I'm glad to hear the effects are detectable. I suppose my next question would be what exactly are the effects? I'm guessing they would be changes to the orbits:
To take an example - the effect of gravity between Mars and Earth.
As Mars orbits the sun at...
Hi there.
