overhead when viewed from the Earth's North Pole or South Pole A
similar concept also applies to other planets Its position remains
fixed as compared to other stars Pole Star can be found by locating
the Big Dipper The Big Dipper is a cluster of stars consisting of 7
bright stars, forming a dipper Astronomers name it "Ursa Major,"
Locate that in the sky Once you locate it, imagine a line
connecting the two stars at the front, continue a line from those 2
stars to the side to a distance 5 times that between the 2 stars,
and you will arrive at (or very close to) the "POLE STAR" which is
a faint star Its altitude (the angle it makes with the horizon) is
always equal to the latitude of the observer Since the altitude of
the Pole star is always equal to the observer's latitude, if you
