The direction of rotation of planets is defined with a reference object that is considered as an almost fixed object in space for all planets. So here below you can find how planets rotate around their own axis? While revolution around the sun in an almost elliptical orbit, all the planets rotate around their own axis.

One is revolution motion (the planet’s motion around the sun), and the other is rotation motion (the planet’s motion around its own axis). There are two types of motion all the planets have in our solar system. The eccentricity of these elliptical orbit varies for all planets and Mercury has the most eccentric orbit. In the solar system our 8 planets Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune revolve around the sun in an elliptical orbit. In which direction do planets revolve around the sun? So basically the objects in our solar system revolve around the sun because of the gravity of the sun and its own velocity and this the reason for the revolution of planets around the sun in an orbit. These paths are called the orbit of the particular planet and the shape of these orbits are elliptical (most likely a circle). While Einstein’s general relativity theory gives a precisely accurate result to understand the orbital path of even Mercury.īecause of the gravity of the sun, planets are not capable of escaping from a certain path in a shape most likely to a circle around the sun. Mercury has the most elliptical planetary orbit in our solar system and Newton’s gravity law was unable to explain it. In this theory precession of the planets orbit and frame-dragging led the astronomers to a better understanding of the revolution of planets around the sun.

(Read about– Einstein’s general theory of relativity).

The General Relativity Theory gives the highest accuracy to understand the orbital motion of the planets. The heavier objects curve the space-time more compare to the lighter objects. R – the distance between the sun and the planet ⇒ Revolution of planets by Einstein’s general relativity theoryĪccording to Einstein’s general relativity theory, gravity is due to curvature of the space-time. Where G is the gravitational constant and its value is 6.67 × 10 -11 Nm 2/kg 2 Gravitational pull or centripetal force due to the sun, F= G×M1×M2/r 2 The gravitational pull of the sun is equal to the centripetal force that always acts inward.

But the centripetal force applied due to the sun’s gravity pulls these planets and makes a curved or elliptical orbital path. Sun is the heaviest object of our solar system so it develops the strongest gravitational pull.Īccording to the initial velocity of planets, they want to travel in a straight path. In the same way gravity of the sun pulls the planets. When we drop any object it falls on earth due to gravitational pull. ⇒ Revolution of planets by Newton’s lawĪccording to Newton, gravity is a force and is the reason planets orbit the sun. Whereas Einstein’s general relativity of theory gives an accurate calculation of the orbital revolution of planetary bodies. The revolution of planets around the sun approximately follows Newton’s law of gravity but not totally. This makes an equilibrium between the force of the sun’s gravitational pull and forces developed by the planet’s initial velocity.Ĭheck About:- Gravity and Gravitational Force The gravity of the sun pulls these planets towards the center of the sun but the velocity of these planets is perpendicular to the force of the sun’s pull. Our 8 planets also got initial velocity in a certain direction. Initially, these bodies have velocity due to the explosion in a certain direction. So due to the explosion and gravitational collapse of a giant cloud formed a system called the solar system in which our sun, 8 planets and their moons, dwarf planets and their moons, asteroids, and other bodies exist.
