On the evening of Monday 8 November we will be able to admire a magnificent one in the sky Astral conjunction between the crescent moon and the “Planet of Love” Venere. It will be the second celestial duet of the month, after the one between Moon and Mars which occurred on November 4th. The meeting will precede by three days the most spectacular astral conjunction of November, which will have as protagonists the Moon and the two gas giants of the Solar system, the Lord of the Rings” Saturn and the largest planet orbiting the Sun, Jupiter. For Friday 19 instead the meeting between the Full moon and the open star clusters of Iadi and of Pleiadi; the longest lunar eclipse of the century will take place on the 19th, which unfortunately will only be partially visible from Italy.

On November 8, the embrace between the Earth’s satellite and the planet Venus will occur in the late afternoon in the South West, in the heart of constellation of Sagittarius and just below the constellation of the Shield. The crescent moon will be visible on the sky throughout the day, while Venus will become visible around 17:00, as soon as i sunrays they will fade, making way for the darkness and the firmament (weather permitting). The planet will be located a few degrees away from the Moon, slightly lower and to the right, as seen from the simulation below. Locating the planet with the naked eye will be very simple. Venus, in fact, is the third brightest object of the celestial vault after the Sun and the Moon, moreover its light (reflected) is so intense as to make it appear as a sort of spotlight hanging from the sky, impossible to confuse with the surrounding stars.

The remarkable luminosity of Venus is linked not only to its proximity to the Earth, but above all to its dense and corrosive nature atmosphere, characterized by the most devastating greenhouse effect of the Solar system. Suffice it to say that its surface temperature reaches 464┬░ C, sufficient to melt the lead. Venus is therefore even hotter than Mercury, the planet closest to the Sun. On Monday 8th the infernal celestial body will accompany the crescent moon until about 19:15 (Rome time), when it disappears beyond the horizon. The Moon will follow him within half an hour.

To observe the astral conjunction of November 8, no specific tools will be required, even if with a telescope, a binoculars or one camera with discreet lens it is possible to identify several details in more of the two objects. Through an astronomical camera connected to the computer and the telescope it is also possible to easily observe the phases of Venus, very similar to those of the Moon. It was precisely by analyzing the phases of the planet of love that Galileo was able to confirm the heliocentric system (with the planets revolving around the Sun) proposed by Niccol├▓ Copernico years earlier.
