As the Sun sets in the sky I rise. I'm approximately 238,900 miles away
from the earth
(384,000 km.). I'm 2,000 miles in diameter and 6,800 miles around. I'm moon is approximately
one-fourth the size of Earth. Some astronomers and scientists think I, the moon, was formed 4.5 billion years ago. Some people have a theory that some dust and rocks hit the earth, bounced off
landed where I am now and formed me. At night I, the moon, is the biggest and brightest light. I outshine all the planets and stars. The reason the earth gets light from me is because the sun's light reflects on me and beams down on the earth. I'm the earth's only natural satellite. You know how the moon has craters, well they were formed by mereoroids hitting the moon.
The Phases of the Moon
When there is no Moon it is a New Moon. A New Moon is when the Moon's phases start over. It is also the beginning of the Moon's phases.
In a few days the lighted part of the Moon is the part you can see forming a cresant.
When the Moon is a qrarter ways around the Earth you can see half of it.
When the shape of the moon is in between a First-Quarter Moon and Full Moon, it is a Gibbous Moon.
About two weeks after a New Moon has come, you can see all of the Moon. The Moon is now half way around the Earth.
When the Moon is in between a Full Moon and a Last-Quarter Moon it is once again a Gibbous Moon.
When the Moon is three quarters of the way around the Earth it is the Last-Quarter Moon phase when we can see half of the Moon again.
The last Moon we see in the sky before a New Moon is a Cresant Moon again.
It takes about one month to see any of the phases of the Moon before they can begin again.
A Blue Moon happens when there is a Full Moon twice in one month. This year, in 1999, there was two Blue Moons. One in March and one in January. There hasn't been two Blue Moon's in one year for 135 years.
