The Stars and planets, galaxies and nebula when you look at the night sky for hours, you can enjoy its treasures. Even simple knowledge of the constellations and the ability to find them in the sky - a very useful skill. You will take great pleasure when being in nature, you'll be able to find some constellations and show them to their companions. The Northern hemisphere of the sky "inhabit" such beautiful constellations, like the Big and little dipper, Cassiopeia, Cepheus and others. We will focus on the polar constellations of the Northern hemisphere, the constellations around the celestial North pole.
Northern hemisphereThe easiest way of orientation in the night sky of the Northern hemisphere is to first find the Big Dipper. This constellation also resembles a ladle. Further, if we continue the line connecting the two front stars of the dipper, towards the upper part, at a distance of approximately 30 degrees you will find the North star. To measure this distance, you do not need a complex astronomicheskie devices. For this there is a simple method. Extend your arm in front of you and make so-called "goat", right pinky and index finger and bending two fingers between them. The distance between the little finger and forefinger "goats" located at arm's length from your eyes, corresponds to roughly 10 degrees on the celestial sphere. Thus, he counted three such distance in the specified direction, you will find a bright star called Polaris. A characteristic feature of this star is that the entire Northern hemisphere revolves around it. This property like to use photographers, making impressive actually with many hours of exposure. Contrary to popular belief, the North Star is not the brightest star in the Northern hemisphere. That title belongs to Arcturus, which is located in the constellation of Bootes.

constellation in the Northern hemisphereThe polar Star is included in another well-known constellation - the Small Bear. This constellation as the Big dipper, like a small ladle, the end of the handle which determines the polar Star. Cassiopeia - another constellation that adorns the Northern hemisphere. It is very easy on a clear night sky for the characteristic shape, resembling the letter "M" or "W" of the English alphabet. This constellation is easy to Orient with the Polar star, as "turn" or the bottom of the letter "M" pointing in the direction of URSA major.

The Following constellation, framing the North pole of the sky is Cepheus. In this constellation of five stars that make up the "house", although this image does not match its astrological significance. The roof of the "house" pointed toward the North star. A more reliable method to find Polaris using the constellation Cepheus, is to continue the right side of the "house" formed by stars al'deramin and Alfirk up.the brightest star of the Northern hemisphere At a distance approximately equal to two sides of the house, you will find the North star.

The Last of the polar constellation in the Northern hemisphere is the constellation of the Dragon. It can be found, knowing that the Cepheus is between the Dragon and Cassiopeia. The dragon is the enormous constellation, constituting the Northern hemisphere of the sky, but the least known. The reason for this is that it is difficult to observe in urban areas where night lighting illuminates the sky, and in rural areas, where the constellation is mixed with many minor stars located in the constellation.
