2. The season in that
`
place or location also
affects the
constellation that we
may see.
Example: Constellation TAURUS is not visible here in
the Philippines during the months of summer but
may again be seen during rainy season months.
`
2. Constellation we
see are not the same
at different times of
the year due to the
revolution of the
earth on its own
orbit around the sun.
`
The apparent
movement of stars `
through night is
due to the
rotation of earth
on its own axis.
Stars move from East to
West direction.
