Difference between Rotational and Translational Motion

The solar system is the planetary system in which, along with seven other planets and other astronomical bodies, the Earth is located. All of these revolve around the Sun which is the only star in the system. The great size of this star makes it have a great gravitational force which constantly attracts all the planets and bodies of the solar system. The fact that the planets revolve around the Sun, each following its own orbit, is a consequence of the gravitational attraction of the Sun combined with the force of the initial orbital energy . Therefore it is safe to say that the planets are not static and are in constant motion. The Earth, for example, performs at least 4 different types of movements, among which rotation and transltion are the best known.

Rotatory motion
Translation movement
Definition It is the movement of the Earth in which it turns or rotates on its own axis (terrestrial axis). On the other hand, the movement of translation is in which the Earth rotates or moves following an elliptical orbit around the Sun.
Duration It takes the Earth 23 hours, 56 minutes, and 4.1 seconds to complete this lap. This movement is from west to east. The translation movement is completed every 365 days and 6 hours. During this time, the Earth travels 930 million kilometers. This results in the Earth moving at a constant speed of 106,200 km/h.
Results The rotation movement results in the succession of day and night and the existence of the cardinal points. In addition, the force exerted by this movement of the Earth causes the poles to flatten while the central part of the planet widens. On the other hand, the succession of the seasons of the year (spring, summer, autumn and winter) are a direct consequence of the movement of translation. Also, the translation of the Earth gives rise to eclipses
