Earth, two types of eclipses occur: lunar, the blocking of the Moon by Earth's shadow, and solar, the obstruction of the Sun by the Moon. When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth.Thus, at any single location on Earth, a total solar eclipse occurs only once every 300 years or so. Because the shadow cast by the Earth is quite a bit larger than the Moon, lunar eclipses are more common than solar eclipses, and totality can last for about an hour.A lunar eclipse occurs when the Moon passes directly behind Earth and into its shadow. This can occur only when the Sun, Earth, and Moon are exactly or very closely aligned (in syzygy), with Earth between the other two. A lunar eclipse can occur only on the night of a full moon.Solar eclipses can only occur during a New Moon when the Moon moves between Earth and the Sun and the 3 celestial bodies form a straight line: Earth–Moon–Sun. ... There are 3 kinds of solar eclipses: total, partial, and annular. There is also a rare hybrid that is a combination of an annular and a total eclipse.A eclipse occurs when the Sun, Earth and Moon are in the same line. For a lunar eclipse, the Earth is in between and its shadow is cast on the moon. ... During a new moon, we see the side of the moon that is not lit up by the sun. However, here too, the moon's shadow doesn't fall in the earth, blocking out the sun.The Moon's Two Shadows. An eclipse of the Sun (or solar eclipse) can only occur at New Moon when the Moon passes between Earth and Sun. If the Moon's shadow happens to fall upon Earth's surface at that time, we see some portion of the Sun's disk covered or 'eclipsed' by the Moon.What is the difference between lunar eclipse and no moon? A lunar eclipse occurs when the Moon passes directly behind the Earth into its umbra (shadow). This can occur only when the sun, Earth, and moon are aligned (in "syzygy") exactly, or very closely so, with the Earth in the middle.
