Which occurs when one planetary body passes through the shadow of another?

When one planetary body passes through the shadow of another, it is called an eclipse. In our solar system, this typically refers to a solar eclipse, where the Moon blocks the Sun's light from reaching the Earth, or a lunar eclipse, where the Earth casts its shadow over the Moon. These celestial events demonstrate the alignment of the Sun, Earth, and Moon, and can create stunning visual displays in the sky.
