Circular orbital velocity.

  1. Mar 19, 2009 #1
    If you are at the distance R from a planet and you want to achieve a circular orbit your velocity must be Sqrt[Gm/R] perpendicular to the radius vector.

    But what if you launch at an angle (ie no longer perpendicular to the radius)? Is it still possible to achieve a circular orbit if the perpendicular component is still Sqrt[Gm/R]?

    Mt guess is that you will end up with some sort of ellipse.

    You will definitely have a non-circular ellipse.
