For the first time since 1226, Jupiter et Saturne seront suffisamment proches pour se sentir comme une double planète, disent les astronomes de l’Université Rice. Ce phénomène peut être observé à l’œil nu au crépuscule le 21 December

Selon les astronomes américains de l’Université Rice, Jupiter et Saturne apparaîtront très proches l’un de l’autre, sous la forme d’une double planète, the 21 December, communiqué de presse sur la physique

Alignments between these two planets are rather rare, occurring once every 20 about years. However, une telle convergence ne s’est jamais produite depuis le Moyen Âge, comme l’explique l’astronome Patrick Hartigan:

À l’approche de Jupiter et de Saturne depuis l’été, ils seront séparés par moins du diamètre d’une pleine lune le 21 December

Le soir du solstice d’hiver, “De l’approche la plus proche, elle ressemblera à une double planète séparée par seulement 1/5 du diamètre de la pleine lune”, pursues the astronomer

Bien que les meilleures conditions d’observation soient proches de l’équateur, l’événement sera visible de n’importe où sur Terre, if time allows it, les planètes apparaîtront bas dans le ciel pendant environ une heure après le coucher du soleil tous les soirs pendant la période susmentionnée, a déclaré M.Hardigan

La prochaine fois qu’ils s’aligneront de près, it will be the 15 mars 2080, selon l’astronome. Ensuite, ce phénomène ne se reproduira pas avant 24h00
