1. In physics, an orbit is the gravitationally curved trajectory of an object, such as the trajectory of a planet around a star or a natural satellite around a planet.
2. Normally, orbit refers to a regularly repeating trajectory, although it may also refer to a non-repeating trajectory.
3. To a close approximation, planets and satellites follow elliptic orbits, with the central mass being orbited at a focal point of the ellipse, as described by Kepler's laws of planetary motion.
4. Within a planetary system, planets, dwarf planets, asteroids and other minor planets, comets, and space debris orbit the system's barycenter in elliptical orbits. A comet in a parabolic or hyperbolic orbit about a barycenter is not gravitationally bound to the star and therefore is not considered part of the star's planetary system.
5. Bodies which are gravitationally bound to one of the planets in a planetary system, either natural or artificial satellites, follow orbits about a barycenter near or within that planet.
6. Owing to mutual gravitational perturbations, the eccentricities of the planetary orbits vary over time. Mercury, the smallest planet in the Solar System, has the most eccentric orbit.
7. The orbit of a planet around the Sun is an ellipse, with the Sun in one of the focal points of that ellipse. [This focal point is actually the barycenter of the Sun-planet system; for simplicity this explanation assumes the Sun's mass is infinitely larger than that planet's.] The planet's orbit lies in a plane, called the orbital plane
8.n the case of planets orbiting a star, the mass of the star and all its satellites are calculated to be at a single point called the barycenter.
9. nce in orbit, their speed keeps them in orbit above the atmosphere. If e.g., an elliptical orbit dips into dense air, the object will lose speed and re-enter (i.e. fall). Occasionally a space craft will intentionally intercept the atmosphere, in an act commonly referred to as an aerobraking maneuver
10. Orbit is the path of a body as it moves under the influence of a second body. An example is the path of a planet or comet as it moves around the Sun.
11. Orbit is a word we hear quite often. Every time the Space Shuttle lifts off the launch pad, we hear it
12. Orbits are elliptical in shape, this means they are similar to an oval. For the planets, the orbits are almost round.
13. The orbits of comets have a different shape.
14. They are highly eccentric or "squashed." Satellites that orbit the Earth are not always the same distance from the Earth.
15. Sometimes they are closer, and at other times they are farther away. The closest point a satellite comes to the Earth is called its perigee
16. The farthest point is the apogee
17. The time it takes a satellite to make one full orbit is called its period. The inclination is the angle the orbital plane makes when compared with the Earth's equator.
18. An object's momentum and the force of gravity have to be balanced for an orbit to happen
19. Low-Earth Orbit (LEO) is restricted to the first 100 to 200 miles of space. LEO is the easiest orbit to get to and stay in.
20. Satellites that seem to be attached to some location on Earth are in Geosynchronous Earth Orbit (GEO)
