A lunar eclipse occurs when the moon passes directly behind the earth into its umbra. This can only occur when the sun earth and moon are aligned exactly or very closely so, with the earth in the middle. Hence the lunar eclipse can only happen the night of a full moon.
What phase of the moon does the lunar eclipse occur
Full moon phase
What shadow causes a lunar Eclipse
Umbra

Length of rotation
Earth rotates every 24 hours with respect to the sun
Length of revolution
365 earth days
Cause of seasons
Seasons are caused by the tilt of earths axis. The earth has a tilt of 23.5 degrees
