what is the period of eclipses?
user
a lunar eclipse occurs when the earth's shadow covers the moon, while a solar eclipse occurs when the moon covers the sun. eclipse periods vary depending on their type but generally last between 2 to 3 hours. lunar eclipses typically occur once every six months, while solar eclipses occur once every 18 months. in rare cases, total eclipses can occur more frequently, with a cycle of roughly one every 175ths of a year.
