    Orbital velocities for various altitudes, for a story I'm writing.
    Comment/Request
    WOW! Just noticed all the other calculators. This is when the word 'awesome' is appropriate.

    Purpose of use
    To verify calculated answers, and find out what mistakes I may have made or steps missed in calculations.Very useful website.Thank You :-)

    Can you add rendezvous with ISS, Inclination changes, time for burn, launch inclinations for orbit and rendezvous?
    Thank You!

    Purpose of use
    Trying to compute solar escape velocity from Pluto''s orbit (NOT from the surface of Pluto, or from orbit AROUND Pluto.)
    Comment/Request
    I wish the variables M, R and r were explained or shown in the diagram. What do they refer to? In my question (trying to compute solar escape velocity from Pluto''s orbital altitude, is M the mass of the Sun? Is R Pluto''s orbital distance from the Sun? Why are the units for R and r different? Etc.

    Purpose of use
    To determine the range of velocities of impact debris from a meteor strike on the Moon that would wind up in orbit around Earth (that is, between Lunar escape velocity and the minimum velocity that would allow correctly aimed debris to leave Earth''s vicinity). Also later to get escape from Saturn parameters from Saturn''s moon Titan.
