(Astronomie)Terre. Note d’usage : Utilisé généralement sans article défini, comme les autres planètes.
Earth is the third planet from the Sun.
Given Kepler’s laws and knowledge of the distance of Earth from the Sun, one can work out the distances to the other planets merely by determining the time it takes each to rotate once around the Sun, that is, the period of the orbit.— (Jonathan I. Lunine, Earth: Evolution of a Habitable World, 2013, ISBN9781107328167, p. 14)
