Orbit

An orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or of a natural satellite around a planet. Orbits are the result of the balance between the forward motion of the orbiting object and the gravitational pull of the primary body it is orbiting. This balance leads to a stable, repeating path. The concept of an orbit is fundamental in astrophysics and celestial mechanics. In Hebrew, "orbit" is translated as מסלול (msalul). In other languages, "orbit" is orbite in French, Umlaufbahn in German, and órbita in Spanish. Key contextual information includes Kepler's laws of planetary motion, which describe the motion of orbiting bodies, and Newton's law of universal gravitation, which explains the force driving orbital mechanics. Understanding orbits is crucial for space exploration, satellite technology, and predicting celestial events.

Orbit
In celestial mechanics, an orbit is the curved trajectory of an object under the influence of an attracting force. Known as an orbital revolution, examples include the trajectory of a planet around a star, a natural satellite around a planet, or an artificial satellite around an object or position in space such as a planet, moon, asteroid, or Lagrange point. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory. To a close approximation, planets and satellites follow elliptic orbits, with the center of mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion.
