The mass of the Sun and the planet, and their distance.
The planets revolve around the sun in elliptical orbits due to the force of gravity. This motion is a result of the initial velocity and gravitational pull from the sun. The time it takes for a planet to complete one revolution around the sun is called its orbital period.
All the models explain retrograde motion because it is such an obvious phenomenon. In Copernicus's model an outer planet goes into retrograde motion when the inner planet overtakes it so that it appears from the inner planet to be going backwards along the ecliptic.

Planets move in orbit because of their own inertia and the gravity of the sun. The sun pulls things to it, and the inertia of a body wants to send it off on a tangent from the arc along which it is traveling. Between the two, bodies will carve out an orbit around the sun.
All planets in our solar system, along with most particles and debris, rotate around the Sun in a counterclockwise direction when viewed from above the Sun's north pole. This motion aligns with the direction of the Sun's own rotation and is a result of the solar system's formation from a rotating disk of gas and dust. The orbits of the planets are also generally elliptical rather than circular.
One result of gravitational forces in the Solar System is the motion of planets in their orbits around the Sun. These forces also contribute to the stability of the Solar System by holding celestial bodies in place and preventing them from drifting off into space.
The rings around the planets are made of gas and rubbish as a result of pollution from Earth
The planets orbit because of gravity and their momentum. They are constantly flying away from the sun, but at the same time are being pulled toward it by gravity. The end result is that they stay moving in a circular motion around the sun.

Motion is the act of changing position or location in space. A push or pull can cause an object to move, but not all motion is the result of a push or pull - for example, planets moving in their orbits.
The positions of the planets change in relation to the background stars due to their orbits around the Sun. As the planets move along their orbit at different speeds, their position relative to the background stars appears to change from our perspective on Earth. This phenomenon is known as planetary motion and is a result of the planets' orbital dynamics.

Yes, both Mercury and Venus can experience retrograde motion. This is a result of their orbits being closer to the Sun than Earth's. When observed from Earth, their apparent motion sometimes appears to be moving backward against the background of stars before resuming its normal direction.
The Sun's gravity is trying to pull the planets towards it. But the planets have their own velocities and all the Sun's gravitational attraction is needed to stop the planets moving away from the Sun. The result is that the planets orbit the Sun.
