There are a couple of popular ways of specifying the location of a celestial object. The first is what you would probably use to point out a star to your friend: the altitude-azimuth system. The altitude of a star is how many degrees above the horizon it is (anywhere from 0 to 90 degrees). The azimuth of a star is how many degrees along the horizon it is and corresponds to the compass direction. Azimuth starts from exactly North = 0 degrees azimuth and increases clockwise: exactly East = 90 degrees, exactly South = 180 degrees, exactly West = 270 degrees, and exactly North = 360 degrees = 0 degrees.
The Northern Star is a constantly fixed point in space marked by a star to help aid in navigation by early sailors to stay on course during the night.The North Star is the star which lies closest to a point in the sky above the northern polar axis of the Earth.This star is called Polaris or the Pole Star.fter the Sun, the brightest star is Sirius, in the constellation Canis Major. However, while Sirius is the brightest star visible from the Northern Hemisphere, it is part o â¦ f a southern hemisphere constellation.
