📚 Topic Summary
A solar eclipse happens when the Moon passes between the Sun and Earth, blocking the Sun's light. Imagine the Moon casting a shadow on Earth! A lunar eclipse, on the other hand, occurs when the Earth passes between the Sun and Moon, casting a shadow on the Moon, making it appear dim or reddish.
