Yes. T = (2pi / sqroot of GM) multiplied by the radius^3/2. A planets mass DOES NOT affect its orbital period. A planets radius DOES affect its orbital period.
With gravity and inertia. If you dont know what those look them up in a scientific dictionary.
gravity is something that can affect the planets.
Gravity holds everything together in the galaxy. (planets)
yes it does
Inertia keeps the planets revolving around the sun instead of just running into the sun. Since gravity pulls masses together, without inertia, all the planets would be pulled into the sun.

Inertia does not affect gravity, these are two entirely separate things, even though they both are produced by the same thing, which is mass. Mass creates both inertia and gravity, but inertia and gravity do not affect each other.

Zero gravity does not affect inertia. The inertia of an object is an inherent property of the object and is directly proportional to the object's mass.

The planets' own gravity has made them spherical. Also there are other effects such as their ability to retain an atmosphere, etc. The Sun's gravitycauses the orbits of the planets.
The effect is very small.
