The moon is actually egg shaped due to the earth's gravitational pull.
4.5 billions years ago a planetary body slammed into the Earth blasting rock debris
into space. Some of that debris went into the Earth's orbit and formed the moon.
About forty percent of the moon's surface will never be seen from Earth.
Much like the Earth, the crust of the moon is composed mostly of silicates, basalt
and feldspar; the mantle iron and magnesium; and the minimal core nickel and iron.
Lunar Orbiter II took several photographs in November 1966 that showed several
obelisks, one of which was more than 150 feet tall, the spires were arranged in
precisely the same way as the pieces of the three great pyramids here on Earth.
Eighty-four percent of the moon's surface is covered by craters as there is no
atmosphere to protect it from meteors and other space debris.
The Lunar Orbiter photographed an amazing spire that towers 5 miles over the
surrounding surface of the moon. Nothing on Earth even comes close.
The moon is very slowly moving away from the Earth at approximately the rate of
an inch and a half a year.
There is no erosion or wind on the moon, as such our astronaut's footprints will
most likely remain for the remainder of the moon's life.
To this day, nobody can explain why the the moon is exactly the right distance and
the right diameter, to completely cover the sun during an eclipse.
