satellite: [16] Satellite comes via French satellite from Latin satelles ‘attendant, 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.
