3 History Theory What is celestial mechanics? Branch of astrophysics that deals with the motions of celestial objects: stars, galaxies, planets, (artificial) satellites, etc.. The field applies principles of physics to produce ephemeris data.
4 History Theory History Started probably when human discovered movement on the celestial sphere, however, problem of planetary motion has been known to Babylonian astronomers (3000 yrs bp). Notable astronomers in the field Aristarchus of Samos creator of the heliocentric model, proved later by Seleucus of Seleucia; Claudius Ptolemy author of the Almages, explained epicycles; Nicolaus Copernicus ; Galileo Galilei; Johannes Kepler; Isaac Newton; Joseph-Louis Lagrange.

7 History Theory Types of orbits Centric classifications: galactocentric, heliocentric, geocentric, areocentric, lunar... Altitude classifications: LEO, MEO, GEO, HEO... Inclination classifications: polar, equatorial... Eccentricity classifications: circular, elliptic, parabolic, hiperbolic... Synchronous classifications: synchronous, geosynchronous, supersynchronous (disposal/graveyard), heliosynchronous...
