- Homework Statement
- Calculate the escape velocity of our solar system.

- Relevant Equations
- v=√(2GM/r)

I'm pretty confused by this but I have a few thoughts. Since the sun takes up most of the mass of the solar system, I was thinking maybe I'm really looking for the escape velocity of the sun? So I would use the mass of the sun for M and the radius of the sun for r. My other thought was to add up the masses of all the planets for M and use the radius of the solar system for r, but I'm not sure that makes as much sense because each planet has its own gravitational field. Any help would be appreciated!
