Спутник-1, romanized as Sputnik-Odin (pronounced [ˈsputnʲɪk.ɐˈdʲin]), means 'Satellite-One'. The Russian word for satellite, sputnik, was coined in the 18th century by combining the prefix s- ('together') and putnik ('traveler'), thereby meaning 'fellow traveler', a meaning corresponding to the Latin root satelles ('guard, attendant or companion'), which is the origin of English satellite.[14] In the Russian language, sputnik is the general term for the artificial satellites of any country and the natural satellites of any planet.
