Moon Phase?
New Moon
When we see the New Moon, the lighted side of the Moon
faces away from the Earth. The Moon is between the Earth
and Sun. We don’t’ see the Moon because the sunlight falls
on the side of the Moon which is turned away from us.
Moon Phase?
Waxing Crescent
“Wax On” = moon on right side; Crescent = small
When we see the Waxing Crescent, a small part of the
Moon appears lighted and it appears to be getting larger
each day. The Waxing Crescent Moon is a narrow
crescent, lit on the right side.
Moon Phase?
First Quarter
When we see the First Quarter, the right half of the
Moon appears lighted, with the lighted part growing
larger on the following days. The First Quarter Moon
is 7 or 8 days after the New Moon.
Moon Phase?
Waxing Gibbous
“Wax On” = moon on right side; Gibbous =
fat/hump
Gibbous means hump. When we see the Waxing
Gibbous Moon, more than half of the Moon appears
lighted. When more than half of the Moon is lit on the right
side, it is a Waxing Gibbous Moon.
Moon Phase?
Full Moon
Two weeks after the New Moon (14 days), the
Full Moon appears. When we see the Full Moon,
the lighted side of the Moon faces toward Earth.
It is opposite the Sun in the sky.
Moon Phase?
Waning Gibbous
“Waning Goodbye” = moon on LEFT; Gibbous =
fat/hump
When we see the Waning Gibbous Moon, more than half of
the Moon appears lighted. When the Moon is waning, it
appears to be getting smaller. When more than half of the
Moon is lit on the left side, it is a Waning Gibbous Moon.
Moon Phase?
Third or Last Quarter
When we see the Third or Last Quarter, the left
half of the Moon appears lighted. The Third or Last
Quarter Moon looks like a half-moon lit on the left
side.
Moon Phase?
Waning Crescent
“Waning Goodbye” = moon lit on LEFT; Crescent = small
When you see the Waning Crescent Moon, a small part
of the lighted Moon is visible. It becomes a narrow
crescent lit on the left side. It follows the Sun ever more
closely, until after 29 1/2 days, we have the New Moon
again and the whole cycle starts over again.
Name all 8 moon
phases – starting with
new moon
