Since the Little Dipper (technically called Ursa Minor) is not one
of the brightest constellations in the sky, it may be difficult to lo-
cate from urban areas If this is the case, use the two end stars in
the bowl of the Big Dipper (the pointer stars) Draw an imaginary
line through them toward the Little Dipper They point to Polaris
(see figure 15) The position of the Big Dipper changes during
the year and throughout the course of the night (see figure 15)
When the Big Dipper is low in the sky (i e , near the horizon), it
may be difficult to locate During these times, look for Cassiopeia
instead (see figure 16) Observers in the southern hemisphere
are not as fortunate; the stars around the south celestial pole are
not nearly as bright as those around the north The closest star
that is relatively bright is Sigma Octantis This star is just within
naked eye limit (magnitude 5 5) and lies about 59 arc minutes
from the pole
DEFINITION: The north celestial pole is the point in the
northern hemisphere around which all stars
appear to rotate. The counterpart in the
southern hemisphere is referred to as the south
celestial pole.
Big Dipper Little Dipper
The two stars in the front of the bowl of the Big Dipper point to Polaris
which is less than one degree from the true (north) celestial pole.
Cassiopeia, the "W" shaped constellation, is on the opposite side of the
pole from the Big Dipper. The North Celestial Pole (N.C.P.) is marked
by the "+" sign.
