Answer

The term eclipse is used to describe either a solar eclipse when the Moon's shadow crosses the Earth's surface, or a lunar eclipse, when the Moon moves into the Earth's shadow.

There are four types of solar eclipses: total, partial, annual and hybrid. Total solar eclipses happen when the sun is completely blocked by the moon. Total solar eclipses are only visible from a specific part of the Earth. Total lunar eclipses are when the Moon passes through Earth’s umbral shadow -giving it that red-orange tone. The red-orange glow is caused by the umbral shadow. This is the inner darkest part of the shadow. The reason it has that reddish color it’s because the Sun’s light is passing around the whole circumference of Earth. Partial lunar eclipse is when the Moon passes through only a portion of the Earth’s shadow. Depending on how far in the Moon moves into the shadow, the Moon may or may not get the orange glow.
