SOLAR SYSTEM

Detailed explanation-1: -In the Solar System, the orbits around the Sun of all planets and most other objects, except many comets, are prograde . They orbit around the Sun in the same direction as the sun rotates about its axis, which is counterclockwise when observed from above the Sun’s north pole.

Detailed explanation-2: -The Sun is the star at the centre of our solar system, and all planets orbit around it.

Detailed explanation-3: -In reality, the planets do not all orbit perfectly in the same plane. Instead, they swing about on different orbits in three dimensional space. For this reason, they will never be perfectly aligned.

Detailed explanation-4: -Johannes Kepler’s laws of planetary motion are: The orbit of every planet is an ellipse with the Sun at one of the two foci. A line joining a planet and the Sun sweeps out equal areas during equal intervals of time.

Detailed explanation-5: -The Sun’s gravity pulls the planets in orbit around it, and some planets pull moons in orbit around them. Even spacecraft are in motion through the solar system, either in orbit around the Earth or Moon, or traveling to further worlds, because of gravitational forces.
