A Total Lunar Eclipse Can Last More Than an Hour

A total lunar eclipse can last more than an hour and a half, but a total solar eclipse never lasts more than 7 1/2 minutes. What is the principal cause of the difference?

A) A total solar eclipse always occurs when the Moon is at perigee; it is moving fastest at that time.
B) A total solar eclipse always occurs when Earth is at perihelion; it is moving fastest at that time.
C) Both Earth and the Moon move clockwise in their orbits, as seen from the north. Thus, during a solar eclipse, Earth and Moon are moving in opposite directions, and during a lunar eclipse, they are moving in the same direction.
D) Earth's shadow at the Moon's distance is much larger than the Moon's shadow at Earth's distance. As Earth rotates, this narrow lunar shadow sweeps quickly over any given spot.
