Answers.comÂ® is making the world better one answer at a time. It is relativley rare to observe a solar eclipse because the sun's light is blocked by the moon.
A solar eclipse happens when the moon gets in the way of the sunâs light and casts its shadow on Earth. That means during the day, the moon moves over the sun and it gets dark. Isnât it strange that it gets dark in the middle of the day? This total eclipse happens about every year and a half somewhere on Earth. A partial eclipse, when the moon doesnât completely cover the sun, happens at least twice a year somewhere on Earth. Note: This diagram is not to scale. In this picture, the moon is covering up the sun in the middle of the day.
