Etymology

It is formed from English orbit + -er, from the verb.[1][2][3] The verb comes from the noun; the OED, revised in 2004, records it from 1946, while Etymonline dates it by 1867.[1][2] The noun is from Old French orbite or directly from Medieval Latin orbita, a transferred use of the classical Latin word for a wheel track, rut or course.[2] The Random House Dictionary labels orbiter an Americanism.[3][4]

Earliest recorded meaning

A spacecraft designed to go into orbit, especially one that does not land afterwards: 1951 in Merriam-Webster Unabridged and the Collegiate,[5][6] 1954 in Etymonline,[2] and 1950–55 in Dictionary.com.[3] The OED's first quotation is from 1958, in Adams and others' Space Flight.[1]

Semantic evolution

The word followed the verb orbit, which the OED records of travelling round a celestial object from 1946 and of going into orbit from 1958.[1] Merriam-Webster also applies it to the space shuttle,[5][6] and Collins contrasts the orbiter, which circles a planet without landing, with the lander.[7]
