How often do lunar eclipses occur?

Lunar eclipses occur when the Earth passes between the Sun and the Moon, casting a shadow on the Moon. They are a relatively common event and typically occur at least twice a year, although not all eclipses are visible from all locations on Earth.

There are three types of lunar eclipses: total, partial, and penumbral. Total lunar eclipses occur when the Moon is completely in Earth's shadow, while partial lunar eclipses occur when only part of the Moon is in Earth's shadow. Penumbral lunar eclipses occur when the Moon passes through the outer part of Earth's shadow, and are usually difficult to see.

The frequency of lunar eclipses is affected by a number of factors, including the position of the Moon in its orbit and the tilt of Earth's axis. Some years may have more lunar eclipses than others, and the timing and visibility of each eclipse will vary depending on your location.
