Mo12-L4b: What is a Lunar Eclipse?





                The Moon’s orbit is tilted slightly compared to
                Earth’s orbit. As a result, during most new moons,   Mo12–L4b        What is a Lunar Eclipse?
                Earth is either above or below the Moon’s shadow.

                  A solar eclipse occurs when the Moon crosses
                       directly between the Sun and Earth.
