Astronomy: what does the November sky

The November sky us many surprises. And 'in fact in transition between the stars in summer and winter: the night gets longer, the Sun anticipates increasingly dark, and this gives us a few more hours to observe the sky. It is what, for example, allows us to admire, on the western horizon, the Summer Triangle (Vega, Deneb and Altair, just point your eyes toward the constellation of Orion, which is located beneath the Taurus and the Pleiades).

Unfortunately the few bright planets visible to the naked eye: Mars will shine among them eastward and will be eclipsed by the Moon on Nov. 26. Then Jupiter will be located east of the constellation Leo. The gas giant is unmistakable before dawn and left the last quarter moon on November 14.

The Leonid meteors will join us from the constellation Leo, to the left of Jupiter. The Leonids will enchant 15 to 20 November, with the peak around 18. Be careful not to lose them, it's a performance equal to that of the Perseids, with about 20 meteors per hour. The meteor shower is produced from the residues of a periodic comet (Tempel-Tuttle) whose fragments are crossed every year by the Earth right in the first half of November. In addition, the observation year will be favorable because not disturbed by the light of the moon and will be localized close to the star range Leonids, observable above the horizon from midnight onwards.

Do not forget the swarm of Taurids: 5 to 12 November we can observe meteors generated from the residues of comet Encke, who will join us from the constellation Taurus. They are not numerous, (about 5 per hour) but are distinguished by their color orange and for their slowness.

The Sun is in the constellation of Libra until 23, when it enters into Scorpio. The moon reaches perigee (367,882 km away) 2 at 23:47, while 15 to 02:00 will be in the farthest point from the Earth in its orbit, the apogee (404,337 km). 27 to 23:55 you will find again at perigee (369,824 km).

Position of the planets
Mercury: in the early days of the month is an hour and a half before the Sun, is the period of best visibility in the morning for the current year, in the second half of the month the planet goes down the horizon to become virtually undetectable.
Venus: for much of the month will be very difficult to observe. At the end of the month about half an hour after the sun goes down and it could be possible to see it on the horizon in the western sky still lit by the evening twilight. Crosses the constellation of Libra until the 18th, when he comes for a short period in Scorpio; 23 enters Ophiushus.
Mars is still low on the western horizon, and you can find it at nightfall before his sunset. During the month through almost the entire constellation of Sagittarius.
Jupiter appears in the east before midnight, reaching south before dawn. It will move slowly, retrograde, in the constellation Leo, from the star Regulus and the limit with Cancer.
Saturn: November 18 is in conjunction with the Sun, for a few weeks will therefore be completely undetectable. We will have to wait until December to see it reappear in the morning very low on the eastern horizon.
Uranus: in the early hours of the night you can find the maximum height and culminates in a southerly direction, then subsides gradually to the South-West.
Neptune is observable only in the first part of the night, early in the evening it can be seen to the southwest.

Conjunctions: Moon-Pleiades 7 at 21:30; Moon-Jupiter 15 at 00:30; Moon-Mercury 21 to 06:00; Moon-Venus 25 at 19:30; Moon-Mars 25 at 19:30; Moon-Mercury 26 at 19:30.

Curiosity: the thirteenth constellation
On November 30, the Sun will leave the constellation Scorpius and will enter in the Ophiuchus, what theoretically should be considered the thirteenth constellation, which is passed through the ecliptic (the apparent orbit of the Sun than the Earth) to about 15 days.
