Usually, lunar eclipses (different types) occur about twice a year or more, whereas solar eclipses (varying types) occur three to four times a year.Ī lunar eclipse is visible from any place at night. Since the occurrence of lunar and solar eclipses depends on the specific alignment of the Sun, earth and Moon in the same plane, total eclipses do not occur very frequently. A rare hybrid solar eclipse is a combination of a total and annular eclipse, visible differently from different places on the Earth. An annular eclipse is when the Sun appears as a bright ring outside the darkened circle. A total solar eclipse, as the name suggests, is when the Sun is completely blocked by the moon, only a faint corona radiating out from the eclipse and a partial eclipse is when the Sun is only partially blocked by the Moon. Solar eclipses are of different types too. A horizontal eclipse is when the Sun and the eclipsed moon can be seen together at the juncture of sunrise and sunset. Similarly, during a total eclipse, the moon lies totally in the umbra and completely obscured by the Earth. A partial eclipse is seen when part of the moon enters the umbra, which is the darkest shadow of the Earth where there is no radiation from the Sun. In this case the moon appears darker in some areas than others. Penumbral eclipses happen when the moon happens to fall into the penumbral shadow of the Earth, which is the outer shadow of the Earth. Lunar eclipses are of four types - penumbral, partial or horizontal. The type and extent to which the eclipse occurs can vary.
