1
Next to the sun, the full moon is the brightest
object in the heavens. However, its surface is
rough and brownish and reflects light very
poorly. In fact, the moon is about the poorest
reflector in the solar system.
2
The moon is 238,857 miles from the Earth.
Because it it Earths closest neighbor in space,
we have more knowledge of the Moon that for any
other solar system object except Earth.

The dark areas on the Moon are plains and the
light areas are the mountains that were formed
from the impact when huge asteroids or comets hit
the Moons surface
4
There is no atmosphere on the Moon, so the sky
does not look blue as it does on Earth. Instead,
it is black, even when the sun is shining.

On July 20, 1969, Neil Armstrong became the first
man to step onto the surface of the Moon. He was
followed by Edwin Aldrin, both of the Apollo 11
mission.

The footprints left behind by the Apollo
astronauts will last for many thousands of years
because there is no wind on the Moon. The Moon
has no atmosphere, so there is no weather to
erase the footprints.
7
At all times, half of the Moon is lit by the Sun.
The other half of the Moon facing away from the
Sun is in darkness. As the moon orbits around
the Earth we can see more and more of its lit
side. This process slowly changes. These
changes are called the phases of the Moon.
