The Ursa Minor or Little Bear or Little Dipper, belongs to the Circumpolar Constellations of the Northern Hemisphere. This means that he is always visible. He is mentioned here because of the fact, that on his tail is the star aUMi. Best known as Polaris or the Northern Star. In our time he rests with a minimum deviation (40 arcmin) on the extension of Earth's axis to the north. This gap will be reduced to a minimum of 26.5 minutes in 2100. Then he will justify his name again, for a few centuries, after 25.770 years! Also in 13.727 years, Vega (áLyr - á star in the constellation Lyra) will be the Northern Star! Now however, and for a long time to come, he is on the North Celestial pole and is the center which around revolve, seemingly of course, all the stars for the observer who stands on Earth. He is a bright supergiant, with surface temperature at 7.200 K and he is 2.200 times brighter, with six times bigger mass and 27,000 times larger volume than our Sun! He is relatively bright and stands out because there are not other brighter stars in the area. Nowadays the position of the brightest star holds Sirius. The Polaris is actually the 48th in brightness

So the observer, having as a benchmark the Polaris and knowing, based on the Sky Map, where every constellation is at the time of observation, can recognize him in heaven. This is certainly not simple, but not impossible! In the figure above seems how to find the Polaris if we know where North is and at what Latitude we are standing. Another way is to find the Ursa Major or Great Bear, which is considered easier, and extend five times the opposite side of the tail, to the North. There we will meet the Polaris

Regarding to the Sun Ecliptic, which is a result from Earth's tilt at 23,44°, the above figures are showing the position according to the season and in relation with the Celestial Equator, which is always in the same position, located in an extension of Earth's Equator and in a position to the observer at 90° minus the Latitude. It also seems where on the Sun Ecliptic are the Solstices and Equinoxes marked during the year
