Solar and lunar eclipses don't occur every month because the plane of the Moon's orbit around the Earth is not aligned with the plane of the Earth's orbit around the Sun.

The Moon's path is tilted when compared to the plane of Earth's orbit, so the Moon is not in a direct line with the Sun and Earth. In a solar eclipse, the Moon must be directly between the Sun and the Earth. Similarly, in a lunar eclipse (slightly more frequent), the shadow of the Earth has to fall on the Moon.

How long does lunar eclipse come?

A lunar eclipse can occur multiple times a year, but the frequency can vary. On average, there are about two to four lunar eclipses each year. Lunar eclipses can be partial, total, or penumbral, with total eclipses being less common.


Why don't solar and lunar eclipses occur ever month?

Because the moon phase is irregular


Lunar eclipses occur every 3 years?

Typically, lunar eclipses occur once or twice a year. Because more than half of all lunar eclipses are partial, and because lunar eclipses are visible only from the side of the Earth where the Moon is up, you would generally be able to see a total lunar eclipse every other year or every 3rd year from your location. The rest of the eclipses would be either partial, or not visible from your location. You can check the NASA Eclipse Web Page to see the catalog of all eclipses from 2000 BCE to 3000 AD at the link below.


Why don't we see solar and lunar eclipse every lunar cycle?

We don't see solar and lunar eclipses every lunar cycle because the orbits of the Earth, Moon, and Sun are not perfectly aligned. Solar eclipses occur when the Moon passes in front of the Sun, blocking its light from reaching Earth, and this alignment is not always present. Similarly, lunar eclipses occur when the Earth casts a shadow on the Moon, and this alignment also does not happen every month due to the tilt of the Moon's orbit.


How often do eclipses naturally occur?

There are two main types of eclipses: solar and lunar. Lunar eclipses occur every 6 months. Solar eclipses occur 2-5 times per year. Eclipses can be partial or total. Partial eclipse covers only part of the sun or moon, while total covers the full entity.

Does a lunar eclipse occur every 3 year?

During the 100-year period from 1901 to 2000, there were 228 solar eclipses and 229 lunar eclipses. On the average, that's 2.28 or 2.29 of each kind, for every year, but in in individual year, it can be as many as 4


When can Eclipses of the Moon occur?

Lunar eclipses occur precisely at the full moon.


Why do most people think that lunar eclipses occur more often then a solar eclipses?

Most people may think lunar eclipses occur more often because lunar eclipses are visible from a larger geographic area on Earth compared to solar eclipses. Lunar eclipses also last longer and are easier to observe with the naked eye, making them seem more common. However, in reality, both lunar and solar eclipses occur at about the same frequency.


Do lunar eclipses occur every 3 hours?

No. During the 20th Century, they averaged about 2.3 per year.
