Eclipse

An eclipse occurs when one celestial body goes into the shadow of another. Solar eclipses occur when the moon passes in front of the sun's disk. A lunar eclipse are when the moon enters the shadow of the earth. They're known as an "impressive natural phenomena'. Other celestial bodies play a part in some eclipses. Such as, different planets in the solar system passing behind the sun, like Mercury and Venus. Two eclipses, at minimum, occur annually. Only seven eclipses maximum can occur every year. The year 1935 was the last time the maximum number of eclipses occurred, it will happen again in the year 2160. For an eclipse to take place, the sun, moon, and earth MUST be on the same plane. In a solar eclipse, the sun projects a cone of the moon's shadow onto the earth's surface. In a lunar eclipse, the moon passes in the shadow of earth. According to World Book Encyclopedia, they say it's the darkening of a heavenly body. Eclipses are very easy to predict, because we know the rotation of earth and such. When an eclipse occurs, the sky is still blue, it only darkens. Many animals confuse totality with night, so they prepare for sleep. Temperatures drop more than 20 degrees or more at totality. In a total solar eclipse, the halo shows around the moon, and only seen in certain parts of the world. Partial solar eclipses are seen from 3,000 miles from totality. Solar eclipses should only be viewed with special eye protection.
