That's Kepler's third law. He derived it empirically from Tycho's observational data,
and it can be derived from Newton's law of universal gravitation.
Yes, spot on, good guess . .
They revolve around the SunThey rotate around their axis.They have cleared their orbital neighbourhood.
If a planet doesn't follow its orbital path, then it may crash into other planets, moons and/or other object floating around in space.
The planets would no longer follow their orbital paths around the Sun. They would move away from the Sun and travel in straight lines.
There are estimated to be around one septillion (1,000,000,000,000,000,000,000,000) stars in the universe. Most will have some celestial bodies: space debris if not planets. So which one of these are you interested in?

All massive objects in the solar system feel the gravitational influence of their primary and most follow an orbital path around it - the majority of the mass orbiting the Sun, including planets, asteroids, comets, etc. A common orbital path, such as the planets follow, is shaped like an ellipse with the Sun at the ellipse's focus. Moons which orbit planets follow a smaller orbital path around their primary (for example, the Earth's Moon follows a path around Earth which it completes in about a month). If objects felt mutual gravitational pull of another object but did not have sufficient relative orbital momentum, they would collide.

Planets have elliptical orbits around the sun.
The movement of planets around the Sun is the best analogy to describe the location of an electron in an atomic orbital.
In planetary terms, when referring to the motion of planets and moons etc. the motion is describes as orbiting. Moons are on orbit around planets, while the planets are in orbit around the sun. An orbital motion.
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.
If a planet doesn't follow its orbital path, then it may crash into other planets, moons and/or other object floating around in space.
First of all, gravity causes the orbital movement in the first place - due to the attraction by the Sun, the planets go around the Sun in ellipses. Because planets also attract each other, the orbits may gradually change over time.
The path that the moon follows around the Earth is called an orbit. The planets going around the sun is called revolution. The moon goes around the Earth in a month.
This is known as the planets orbital period. For the Earth, this is one year.
