satellite: satellite: [16] Satellite comes via French satellite from Latin satelles ‘a(chǎn)ttendant, escort’, which itself probably went back to Etruscan satnal. Its use for a ‘body orbiting a planet’ is first recorded in English in 1665, and comes from the astronomer Johannes Kepler’s application of Latin satelles to the moons of Jupiter.
satellite (n.): 1540s, "follower or attendant of a superior person," from Middle French satellite (14c.), from Latin satellitem (nominative satelles) "attendant, companion, courtier, accomplice, assistant," perhaps from Etruscan satnal (Klein), or a compound of roots *satro- "full, enough" + *leit- "to go" (Tucker); compare English follow, which is constructed of similar roots.

Meaning "planet that revolves about a larger one" first attested 1660s, in reference to the moons of Jupiter, from Latin satellites, which was used in this sense 1610s by German astronomer Johannes Kepler (1571-1630). Galileo, who had discovered them, called them Sidera Medic?a in honor of the Medici family. Meaning "man-made machinery orbiting the Earth" first recorded 1936 as theory, 1957 as fact. Meaning "country dependent and subservient to another" is recorded from 1800.
