What is an orbit? Gravitational attraction trajectory

post-title

Meaning of orbit, what it consists of and the shape of the path that represents the movement of celestial bodies and objects in outer space.


Definition of orbit

An orbit can be defined as the elliptical trajectory that a body follows moving in space, comparable to an arched path that an object makes by gravitating around another point in the cosmos.

The planets orbit the sun, while the moon and artificial satellites orbit the earth.

In order for a spacecraft to enter orbit it must pass the atmospheric layer, to do this it is necessary to reach a minimum speed of almost thirty thousand kilometers per hour which corresponds to over eight kilometers per second.

If the speed were lower, the spacecraft would fall back to earth.
