A solar eclipse is a natural event that takes place on Earth when the Moon moves in its orbit between Earth and the Sun. It happens at New Moon, the moon moves between the Earth and the sun, blocking the intensity of the light. Solar eclipses happen about every 18 months and only lasts for a few minutes.
A partial eclipse occurs when the Moon covers only part of the Sun. A total eclipse occurs when the whole Sun is covered when the sun, moon, and earth are in a direct line. When a solar eclipse happens the moon actually casts two shadows on the Earth. One shadow is called the umbra, and it gets smaller as it reaches the Earth. It’s the dark center of the shadow of the moon. The second shadow is called penumbra, and it gets larger as it reaches the Earth.
