A line or circle around the celestial sphere parallel to
and 23°27’ north of the Celestial Equator is called
the Tropic of Cancer.
A line or circle around the celestial sphere parallel to
and 23°27’ south of the Celestial Equator is called

Constellations
A constellation is a group of stars that are in the
same general direction, thus they appear to
be close to each other
though they may be actually be far apart.
Constellations make patterns that are
recognizable and are given names based on
what the patterns suggest, from bears to
heroes from myths
Constellations make it easier to keep track of
the stars in the sky.
