They are all in orbit.
Anything that isn't affected by the Sun's gravity will not revolve it. Almost anything outside of our solar system will not be affected by the Sun's gravity. But that's not to say that they aren't being affected by another star's gravity.
Planet Eris is affected by gravity like any other celestial body in our solar system. It has its own gravitational force that holds objects on its surface and influences other objects around it. Gravity also affects the orbit of Eris as it interacts with other planetary bodies in the solar system.
All planets and other objects in the solar system orbit the Sun because of its gravity.
Gravity is the force which keeps them there.

Gravity!
I'm pretty sure this answer varies.. but.. We can determine a solar system has planets by the wobble of the sun in the solar system. A sun wobbles because of the gravitational pull planets have on it. The effect of the wobble depends on the mass of the planets rotating, and how far they are from the sun. The earth itself has the same wobble effect from the moon. They probably have a tool with a specific name that measures it but I would have no idea what it's called and how it works.
Gravity causes objects, like planets, to orbit the Sun.
Yes, Saturn's rings do have some gravity, but it is very weak compared to the gravity of larger objects like planets and moons. The gravity from Saturn's rings is not significant enough to affect spacecraft or other objects passing through the ring system.
The relationship between mass distribution and effective gravity is that the distribution of mass within a system affects how gravity is experienced by objects within that system. Objects closer to more massive regions will experience stronger gravitational forces, while objects farther away will experience weaker gravitational forces. This means that the distribution of mass can impact the overall gravitational pull experienced by objects within a system.
