From a particular location on Earth, why can we see many more total eclipses of the Moon than total eclipses of the Sun?
the Moon is much bigger in the sky than the Sun
a total lunar eclipse is visible over a much larger part of the Earth’s surface than a total solar eclipse
the Moon is always in the same place in our sky, while the Sun moves around the sky
the line-up of the Earth, Moon, and Sun needed for a lunar eclipse happens many, many times more often than the line-up needed for a solar eclipse
