An
Introduction
to
Lunar
Phases The
moon
is
a
fascinating
astronomical
body
that
has
fascinated
humans
for
centuries.
One
of
the
most
intriguing
aspects
of
the
moon
is
its
various
phases,
which
are
the
different
ways
in
which
the
moon
appears
to
us
on
Earth.
These
phases
are
caused
by
the
changing
angles
between
the
sun,
Earth,
and
moon. There
are
eight
lunar
phases,
which
are:
new
moon,
waxing
crescent,
first
quarter,
waxing
gibbous,
full
moon,
waning
gibbous,
third
quarter,
and
waning
crescent.
The
new
moon
occurs
when
the
moon
is
between
the
sun
and
Earth,
and
we
cannot
see
any
of
the
moon's
illuminated
side.
The
waxing
crescent
phase
is
when
we
can
only
see
a
small
sliver
of
the
illuminated
side.
The
first
quarter
phase
occurs
when
half
of
the
moon's
illuminated
side
is
visible.
The
waxing
gibbous
phase
is
when
most
of
the
illuminated
side
is
visible,
but
the
moon
is
not
yet
full. The
full
moon
is
perhaps
the
most
well-known
lunar
phase,
when
we
can
see
the
entire
illuminated
side.
The
waning
gibbous
phase
is
when
most
of
the
illuminated
side
is
visible,
but
the
moon
is
beginning
to
shrink.
The
third
quarter
phase
is
when
half
of
the
moon's
illuminated
side
is
visible,
but
the
opposite
side
from
the
first

Finally,
the
waning
crescent
phase
is
when
we
can
only
see
a
small
sliver
of
the
illuminated
side,
and
the
moon
is
beginning
to
disappear
from
view. Lunar
phases
are
significant
for
various
reasons,
including
cultural
significance
and
their
effects
on
tides
and
other
natural
phenomena.
Observing
these
phases
can
also
be
a
fun
and
educational
activity
for
amateur
astronomers
of
all
ages.
