So, I've got no real education in physics, etc. and I could definitely use a hand. I'm working on a science-fiction story involving commercialized inter-planetary travel. It seems to me that everything orbits the sun in the same direction, and even comets and the like move in that direction, once they get near enough.
For a vessel which is able to travel in under a month to any planet in its star-system (which, for the sake of argument, let's say is identical to our own,) would it likely be feasible (especially in terms of fuel-usage, the difference in required power, and the physical stress exerted on the vehicle) to shorten a trip by traveling in the opposite direction as its initial orbit? Obviously, this would be a more expensive option, but I'd like to get at least a rough estimate of how much more fuel, power, and vehicular fortitude it would require, or if it would probably be beyond the technology and means of a civilization whose typical starship can at best be expected to make the sort of trip specified above.
Thanks in advance.
