In the first month of 2011 that the planet is best placed to find the comments of course in relation to the current conditions of visibility, it is definitely Venus (on the side, in a telescopic shot of 2004 ). Reaches its maximum western elongation from the Sun on the 8th, getting up three hours and three quarters of the star of the first day, and of course, is the object brightest of hours before sunrise (when there is no moon in the sky).
The other planets are made some more and some less well. The only observable in the evening is Jupiter (in the company of distant Uranus and Neptune), but it always goes down soon. Saturn rises in the morning, but it is still far away from the opposition for next spring, Mars is nearly behind the Sun, while Mercury is found at greatest elongation on 9 morning, almost exactly like Venus, but we must remember that the innermost planet is much less bright and much closer to the Sun
Venus instead of enjoying his best moment of visibility di tutto il 2011. A Capodanno si trova nella costellazione della Bilancia, ed in seguito attraversa brevemente lo Scorpione per finire in Ofiuco. Il tempo per osservarlo diminuisce abbastanza velocemente, poiché mentre il pianeta continua a scendere lungo l'eclittica, il Sole (dopo il solstizio di dicembre) ha ricominciato a salire, facendo guadagnare lunghezza alle giornate. Le dimensioni apparenti del pianeta scendono da 27" a 20", mentre la frazione di disco illuminata passa dal 46% (ampia falce) al 61% (leggermente gibbosa).
Nei giorni intorno alla massima elongazione la fase ammonta a 50% (cosiddetta "dicotomia" di Venere), e per gli astrofili è molto interessante verificarlo: spesso la scattered light in the Venusian clouds makes this visually different value.
A beautiful conjunction with the Moon occurs on the morning of 3rd January.
