Escape velocity of solar system

  1. Jan 16, 2013 #1
    Hey guys so this question I'm kind of stuck on,

    Our solar system, starting from Saturn's orbit.


    So I know the formula is v = sqrt(2GM/r)

    But not sure what to put for the mass and radius, am i including saturn and planets like uranus and neptune only or all the satellites and stuff to like moons, asteroids, etc. Or am I simply over thinking this lol?

    Thank you.

    Look up the percentage of the solar system's mass that is contained in the Sun. Will including planetary masses affect your result significantly?

    Ok so I calculated it to be 13.72 km/s since saturns orbital speed is 9.7 km/s.
