I was just looking at list of solar system objects and was surprised to see that the surface gravity of Uranus is only 90% that of Earth's. I get it that the "surface" of a gas planet is further from that planet's core than is the case for Earth.
But does surface gravity really have any effect on a planet's overall gravitational force toward other objects? For example, would Uranus still have a considerably greater tug on an asteroid passing 100,000 miles away from it than the Earth would have on an asteroid passing by Earth at the same distance?
