Eclipses - Solar and Lunar
Learning how solar and lunar eclipses occur.
Core concept
Eclipses do not happen every month, even though new and full moons occur monthly, because the Moon's orbit is slightly tilted compared to Earth's orbit around the Sun — perfect alignment for an eclipse only happens occasionally. A total solar eclipse, where the Moon completely covers the Sun, can only be seen from a narrow path on Earth, while a lunar eclipse can be seen from the entire night side of Earth at once, making lunar eclipses more commonly observed by any given location.
