  • Uh, you’re right about the acceleration.

    I’m not sure what you’re on about with the second point?

    Are you suggesting that because geosynchronous orbits exist they’re always in geosynchronous? We see big ships (imperials 2’s) in all sorts of different elevations. They’re very clearly not orbiting- anything other than geosynchronous for that planet is going to require some kind of lift to keep it at elevation- and probably some amount of lateral/tangential speed to keep above a city.

    Their repulsors could do the job (but probably bring in the engines for some reason… but we won’t get into that.)

    Or are you suggesting that the orbit around the sun is somehow significant enough to affect the position of a ship able to transit most systems within hours?

    It might be in a heliocentric orbit (along with the planet) but it’s still not orbiting the planet unless it’s moving with a tangential velocity roughly equal to the orbital velocity.


  • I always envision that they’re burning velocity while in hyperspace to come out in a zero-zero rendezvous with whatever they’re meeting so that they come out “just right”

    My head cannon is that the hyperdrive is like sliding into a blister on the edge of space and the drive is pushing that blister. Your momentum is preserved, start and stop but you can shift it so you’re always coming out “stopped” or advancing at a useful direction.

    (Otherwise we’d see them making long-ass RV burns.)

    So the reason the moon has a curved path is because of the earth’s gravity. Its velocity relative to earth is high enough that as the earth pulls the moon at 9.8 m/s2 , it misses the earth entirely. This pulls the moon into a circular trajectory, and that’s what we call an orbit.

    Big ships in Star Wars are not “in orbit” in this sense. They’re relying on technobabble and dohickeys to stay up in the sky- above a specific part of the planet.

    So when those engines stop providing power, they fa ll to the planet.




  • Because there is gravity in space.

    “orbit” is just what we call the sweet spot between moving fast enough to not hit the planet or mooon or whatever and not so fast that you escape it’s gravity (even though it still affects you. just not enough to make kissy noises as you fall back to it.)
