As you may recall from lessons in school, the Moon is a natural satellite of the Earth. Its rotation synchronizes with the Earth’s. It is also the second brightest object in the Earth’s sky right after the Sun. In addition, you learned that the Moon orbits around the Earth once every 27.3 days. Because the Earth is also rotating and orbiting around the Sun, the phases of the Moon occur about every 29.5 days. This quiz will not be on the Moon and its phases but, rather, on the Moon and eclipses. However, the Moon’s phases do directly relate to eclipses.
You already know a little bit about the Moon so let’s look into eclipses. What is an eclipse?
An eclipse is when one object casts its shadow upon another object. There are three parts or types of Earth shadows. There is the umbra, which is the innermost and darkest part of a shadow and comes with a total eclipse of an object. Next is the penumbra which is when a shadow covers only a portion of an object so it is referred to as a partial eclipse. Finally there is the antumbra which is when a shadow appears to cover the center of an object but not the outer diameter of that object. This is known as annular eclipse.
There are two basic forms of eclipses, i.e., a lunar eclipse (meaning the Moon) and a solar eclipse (meaning the Sun).
