orbit
Inertia is trying to keep each planet moving in a straight line, and the sun's gravity is trying to pull each planet into the sun. The resultant of those two vectors is the orbital path each planet follows.

Because they each have a certain path that they follow, and the paths do not intersect.
The time taken for a planet to spin on its axis is called a "day." Specifically, it refers to the period it takes for the planet to complete one full rotation relative to the stars, known as a "sidereal day," or relative to the sun, known as a "solar day." Each planet has a different length of day based on its rotation speed.
Yes. Each moon revolves around its own planet. Our Moon revolves around Earth.
365 days
all parts of the planet pulled each other toward the center of the mass by gravity
For a planet in our solar system, one revolution around the Sun is called a "year." Each planet has a different year. As you know, Earth takes 365.25 days to follow its orbit around the Sun, though Jupiter's year is about 4335 earth days. It all depends on how long it takes each one to revolve around the Sun.
