A geocentric orbit or Earth orbit involves any object orbiting the Earth, such as the Moon or artificial satellites. In 1997 NASA estimated there were approximately 2,465 artificial satellite payloads orbiting the Earth and 6,216 pieces of space debris as tracked by the Goddard Space Flight Center.

| Cladius Ptolemy Greek astronomer and mathematician Modeled the movements of the Sun, the Moon, and the five known planets (Mercury, Venus, Mars, Jupiter, and Saturn) in the skies to great accuracy, with a geocentric system of orbits and epicycles.

In the geocentric system, the Earth is considered to be thecenter of the solar system. The Moon, the planets, the Sun, and the stars allrotate around the Earth (which stays still), with uniform circular motion.They compose the heavens, which are considered to be ethereal and unchanging.
A heliocentric orbit (also called circumsolar orbit) is an orbit around the barycenter of the Solar System, which is usually located within or very near the surface of the Sun. All planets, comets, and asteroids in the Solar System, and the Sun itself are in such orbits, as are many artificial probes and pieces of debris. The moons of planets in the Solar System, by contrast, are not in heliocentric orbits, as they orbit their respective planet (although the Moon has a convex orbit. Satellites in a polar orbit do not have to pass the North and South Pole precisely; even a deviation within 20 to 30 degrees is still classed as a polar orbit. Polar orbits are a type of low Earth orbit, as they are at low altitudes between 200 to 1000 km. Sun-synchronous orbit (SSO) is a particular kind of polar orbit. Confusion Between Orbit and Rotation Geocentric Christians tend to make the argument, 'Why didn't God just come out and say the earth stopped if this was the case?' First of all, God can phrase anything the way He chooses to do it, and if you think that God has to meet your personal standards of phrasing, then the Word of God is not your final authority. A synchronous orbit is an orbit where the orbital period equals the rotation rate of the orbited body. The eccentricity and inclination are not bound to specific values, although to be synchronous the orbit must not intersect with the atmosphere or surface of the orbited body, causing the orbit to change.

Geocentric Orbit Of Mars
- We would be aware of the movement of the ground or the air.
- The apparent position of nearby stars would change in the sky (parallax).
- But why did the planets display retrograde motion, moving both forwards and backwards on the sky?
- And why did the planets appear brighter at certain times than others?
To explain the orbits of the Moon and planets in this system, it was notenough to have them travel on circular paths (deferents) about the Earth.Each one traveled on a small circular orbit (an epicycle) which in turntraveled on a larger deferent about the Earth. This combination, ratherlike the interlocked gears of a mechanical clock or watch, produced a pathwhich matched the observed non-circular elements of the planetaryorbits.
The next figure shows how a deferent (large circle) and an epicycle (smallcircle) could produce both the overall prograde (counterclockwise) and theoccasional retrograde (clockwise) motion of the planet Jupiter under thegeocentric system. The red dot shows the location of Jupiter, and the blue line shows how it would shift forward and backward against background stars.
