    Orbital speed variation as a planet orbits the Sun

    Sorry, "Perimeter" = ellipse circumference "Perioud"= orbital perioud @etotheipi, thnx for your answer, but this method I know. I need an other way

    Orbital speed variation as a planet orbits the Sun

    Sorry for my english, I'm using google translator. I understand so: Mean orbital speed Vm=P/T, where P - perimeter, T - Perioud. For my problem I need Vm=Vi, where Vi - instantaneous orbital speed I need an alternative way to get "r", by ex from Kepler's law. PS: There I'm nub...

    Orbital speed variation as a planet orbits the Sun

    Summary:: At what distance from the Sun will the speed of the planet be equal to the average orbital speed? I'm not sure where to place this question, please move it in the right thread. [Mentor Note -- thread moved from the technical forums, so no Homework Template is shown] At what...
