No, everything in our solar system revolves around the sun
The difference between orbit and rotation is: to orbit is to go around celestial objects (celestial objects means any object in space such as satelittes, other planets et cetera) Now to rotate is to spin around. I.E. the Earth takes 365 days to make one full rotation!
Gravity is the attractive force between any two objects in space. It is responsible for the motion of planets around the Sun, moons around planets, and the formation of galaxies.
No, a planet does not necessarily have to rotate around a star. There are rogue planets that do not orbit any star and instead wander through space independently. These planets are not bound to a specific star and travel alone through the galaxy.
Just about any object in space will rotate - not just asteroids.

None at all.
Massive objects, such as stars and planets, create a gravitational field that distorts the space and time around them. This distortion causes objects to follow curved paths near the massive object, as described by Einstein's theory of general relativity. Essentially, the presence of mass causes space and time to warp in a way that influences the motion of other objects nearby.
It's an object in outer space; that's basically what astronomy is about - studying objects in outer space.
The strength of gravity at any point in space will vary depending on what objects are present, how far away they are, and how much mass they have.
Yes there are millions of objects that orbit Saturn.
When most people think of something rotating around a planet, they're usually talking about a moon. However, since people started going into space, there are also man-made satellites and pieces of debris from spacecraft, such as nuts and bolts. All things that rotate around any object is called a satellite. We are a satellite to the sun where the sun is a satellite to the black hole in the center of our Galaxy.
Yes. The axis would be the center of rotation. Please note that neither the axis of the Earth, or of a galaxy, or of other astronomical objects in rotation, has any physical reality; it is just an imaginary line, around which the object rotates.
