The Earth makes a translational movement around the sun.
A translational movement is one carried out by a body that draws a large curve if we take into account its size. This notion is very common in astronomy , since translational movement is what celestial bodies perform while they describe their orbits.
The term in question is made up of two main words whose etymological origins coincide since both come from Latin. Thus, movement comes from movere and translation emanates from translatio, which can be defined as the action of carrying something from one place to another.
The state of that object that is changing location is known as motion . The term is linked to the verb move , which refers to getting something to leave the position it occupies and move to a different one. Shaking something is also known as moving.
Translation , for its part, is a concept with several uses. It can be about the process and consequences of moving a thing or a person from one space to another; of a kind of rhetorical figure; of translation into a different language; or the movement developed by a body that traces a curve with a wide radius with respect to its own dimensions.
The translational movement of the Earth
The planet Earth , for example, performs four main movements: rotation , precession , nutation and translation. The translational movement is that which our planet carries out around the sun , making an elliptical orbit with an approximate perimeter of nine hundred and thirty million kilometers.
Specifically, the Earth takes a total of 365 days, 6 hours and 9.1 minutes to complete this complete revolution as it moves in outer space at a speed of 108,000 kilometers per hour.
The main consequence of our planet carrying out this translational movement is that the so-called seasons of the year ( spring , summer , autumn and winter ) take place successively. And not only that but because of it in different parts of the globe they are found in different seasons. So, for example, while in Spain we are experiencing winter, in Chile we are enjoying summer.
The celestial bodies develop a translational movement when tracing their orbits.
The heliocentric theory
Fundamental to understanding modern astronomy and its studies is to take as a starting point theories of great importance that have become references, such as the heliocentric theory , which establishes that the entire solar system revolves around the sun . The Polish Nicholas Copernicus is considered the father of that and precisely one of his masterpieces ( "De revolutionibus orbium coelestium" ) is the one that is established as the true germ of modern astronomy.
The research he carried out has been fundamental in the field of science but at the time it was considered by the Church almost as a heresy.
Translational movement and the sun
It is possible to understand, in summary, that the translational movement carried out by the Earth are the rotations it makes around the sun .
While developing this orbit, the planet also carries out a rotation movement , which involves turns on itself along an imaginary line that crosses the poles.
