Orbitálban

Orbitálban is a term used in astronomy and physics to describe the path of an object around another, more massive object. This path is typically an ellipse, though it can also be a circle, parabola, or hyperbola depending on the object's velocity and the gravitational forces involved. The larger object, such as a star or planet, is at one of the foci of the ellipse. The smaller object, like a moon or artificial satellite, follows this orbital path.

Key characteristics of an orbit include its semi-major axis, which defines the size of the orbit, and its eccentricity, which describes how elongated the ellipse is. The period of an orbit is the time it takes for an object to complete one full revolution. Kepler's laws of planetary motion describe the fundamental principles governing these orbits.

Objects in orbit are constantly in a state of freefall. Gravity continuously pulls the orbiting object towards the central body, but its tangential velocity prevents it from falling directly into it. This balance between gravity and velocity results in the continuous curved path we call an orbit. Understanding orbital mechanics is crucial for space exploration, satellite operation, and comprehending the structure of planetary systems and galaxies.
