Forms

planète f (plural planètes)[1] Planete (1119), planestre (Béroul), planet (14th century), planette (1539); written planete by the Académie in 1694 and 1718, planète from 1740[2]. Masculine or feminine in Old French.[2]

Etymology

It is borrowed from Late Latin planēta (“wandering star”) (2nd century), a remaking of the plural “planētēs”,[2][3][4][5][6] from Ancient Greek πλανήτης (planḗtēs, “wanderer”), used in “planêtes astéres” “wandering stars”, as opposed to the fixed stars,[2][3][1] from πλανάω (planáō, “to lead astray; passive, to wander”).[2][7][1] The origin of the Greek verb is obscure.[3]

Earliest recorded meaning

In Philippe de Thaon's Comput (1119) the planets are royal stars que en Latin numum Planetes: wandering stars, including the Sun and the Moon.[2][3]

Semantic evolution

Ancient astronomy counted seven planets, the Sun, the Moon, Mercury, Venus, Mars, Jupiter and Saturn[2][8][9]; Béroul's Tristan already has les set planestres.[2][8][9] In the 14th century the planet was the star thought to rule a person's destiny, hence être né sous une bonne planète (Furetière, 1690).[2][9]

With the new astronomy the word took its modern sense, a body circling the Sun: Fontenelle (1686) writes that the Sun has ceased to be a planet and the Earth has become one.[2][3] Planétaire dates from 1553.[4] In modern use la planète is also the Earth as a whole, à l'échelle de la planète.[10]
