Description
Scaling the Earth down to the size of a basketball, the Moon is roughly the size of a tennis ball. The Moon's orbit correlates closely to the 3-point shooting line of a basketball court. With the floor taken to be the ecliptic plane, the Moon's orbit reaches a maximum height out of this plane about the length of a tennis racket. Eclipses can only occur when the Moon's path crosses through the ecliptic so that the Sun-Moon-Earth, or Sun-Earth-Moon, are aligned.
