Reflets des plan\u00e8tes V\u00e9nus et Jupiter \u00e0 l’aube du 13 f\u00e9vrier. \u00a9 Jean-Baptiste Feldmann<\/figcaption><\/figure>\n

Cette image a \u00e9t\u00e9 r\u00e9alis\u00e9e avec un objectif de 27 mm de focale ouvert \u00e0 3,5 et une pose de 3 secondes \u00e0 3200 iso (bo\u00eetier Nikon D7100).<\/p>\n

V\u00e9nus<\/a> avait commenc\u00e9 l’ann\u00e9e tr\u00e8s haute au-dessus de l’horizon puisque son \u00e9longation maximale \u00e0 l\u2019OUEST du Soleil<\/a> s’\u00e9tait produite le 6 janvier. Elle redescend d\u00e9sormais le long de l\u2019\u00e9cliptique (nous la voyons “retomber” vers l\u2019horizon) et ce ph\u00e9nom\u00e8ne va se poursuivre jusqu\u2019au mois d’ao\u00fbt, date de sa conjonction sup\u00e9rieure (p\u00e9riode pendant laquelle V\u00e9nus vue de la Terre passe derri\u00e8re le Soleil).<\/p>\n

Quant \u00e0 Jupiter<\/a> elle se d\u00e9place en sens inverse : depuis sa conjonction solaire du 26 novembre nous la voyons remonter le long de l\u2019\u00e9cliptique \u00e0 l\u2019aube pour s\u2019imposer de plus en plus longtemps la nuit jusqu\u2019\u00e0 son opposition au mois de juin. Vus de la Terre les deux astres se sont crois\u00e9s le 22 janvier et depuis cette date Jupiter a \u00ab\u00a0d\u00e9pass\u00e9\u00a0\u00bb V\u00e9nus.<\/p>\n

Toutes les plan\u00e8tes tournant autour du Soleil, les d\u00e9placements plan\u00e9taires \u00e9voqu\u00e9s dans cet article sont bien entendus apparents et traduisent uniquement l\u2019impression ressentie par les observateurs terrestres.<\/p>\n","protected":false},"excerpt":{"rendered":"
