Why do we see the Moon?
The Moon does not shine on its own. It is illuminated by the Sun.
Like the Earth, Half the moon is always lit by the sun.
Motions of the Moon 1 Moon Year = 27.3 days to revolve
around the Earth 1 Moon Day = 27.3 days to rotate on its
axis one time
Rotation = Revolution
(orbit)
Which means…….
Why do we only see the same
side of the Moon?
Because the Moon’s rotation on its axis and its revolution around the Earth is the same.
We always see the Near Side!!!
Sides of the Moon We only see the Near side of the Moon. We cannot view the Far side of the Moon
from Earth.
Misunderstanding…There is no ‘dark side’ of the moon. It gets
sunlight, we just cannot view it from Earth.
What are the Moon Phases?
As the Moon revolves around the Earth, we get different views of the near side. These are the phases of the Moon!!!
