Vénus

planet (n.) 

late Old English planete, from Old French planete (Modern French planète), from Late Latin planeta, from Greek planetes, from (asteres) planetai "wandering (stars)," from planasthai "to wander," of unknown origin, possibly from PIE *pele- (2) "flat, to spread" on notion of "spread out." So called because they have apparent motion, unlike the "fixed" stars. Originally including also the moon and sun; modern scientific sense of "world that orbits a star" is from 1630s.

Planète: du grec (asteres) planetai = (étoile) errante

Ça fait penser aux vidéos où les gens zooment sur les étoiles. Même comportement ici... Mais comme il le dit, ce n'est pas tous les jours qu'il a pu constater cet effet.
