Johannes Kepler
All planets orbit around the sun in our solar system. The sun is at the center of our solar system, and its gravitational pull keeps all the planets in orbit around it. The idea of all planets orbiting around the Earth was a historic belief known as the geocentric model, which has been proven incorrect by modern astronomy.
Three rules for consideration for planets are: 1) The planet must orbit a star. 2) The planet must have enough mass to have a nearly round shape. 3) The planet must have cleared its orbit of other debris.
Three types of bodies in the solar system besides dwarf planets, asteroids, and planets are comets, moons, and meteoroids. Comets are icy bodies that release gas and dust as they orbit the Sun, moons are natural satellites that orbit planets or asteroids, and meteoroids are small rocky or metallic bodies that travel through space.
The three main parts of the solar system are the Sun, which is the central star that all other objects orbit around; the eight planets, which include Earth, Jupiter, and Mars; and various smaller bodies such as asteroids, comets, and moons that also orbit around the Sun.
It was a German astronomer by the name of Johannes Kepler who did a whole lot of geometrical calculations from new and unusually accurate observations made by Tycho Brahe. Kepler showed that the planets each move in an elliptical orbit and he gave three laws describing exactly how they move, and it was found to be much more accurate than the previous models of Ptolemy and Copernicus. He did not know why they behaved as they did and we had to wait until Isaac Newton explained it using his new theory of gravity.
Isaac Newton proposed the three laws of motion and also developed the law of universal gravitation, which explains how the planets orbit the sun. This theory provided a unified explanation for both earthly and celestial motions.
The solar system has three classified dwarf planets. They are Pluto, Ceres, and Eris. A dwarf planet has sufficient mass, has not cleared the neighborhood around its orbit, and is in orbit around a star.

Shape, rotation-direction, and orbit-direction.
In fact, Venus, Uranus, and the "dwarf planet" Pluto orbit the Sun in the same direction as all the other planets. So all the planets orbit in the same way.However they rotate in the opposite direction to the other planets.

The orbit of each planet it the path it takes as it rotates round the Sun under the influence of the force of gravity. Every planet has a separate orbit and the orbits all follow Kepler's three laws of planetary motion.

The four outer planets have many moons each, while the inner planets only have three between all of the, two for Mars and one in orbit around the Earth. The planet with the most is Jupiter, with 63 confirmed moons.
Moons are natural satellites that orbit planets, planets orbit stars like our Sun, and stars are part of galaxies that contain planets and moons. Moons are gravitationally bound to planets while planets are gravitationally bound to stars. All three are part of the same interconnected celestial system.
