Eclipse Type Explainer
Used by developers, writers, and creators worldwide.
An eclipse type explainer introduces the different kinds of solar and lunar eclipses and how each one happens. Eclipses are among the most spectacular events in the sky, and they come down to a simple alignment of the Sun, Earth, and Moon. This tool pairs each eclipse type with an accurate description of what causes it. Click generate to learn one, then compare them all. It is ideal for astronomy students, stargazers, and the curious. Each type is matched with its correct cause, so you can trust the science. The key distinction is what lines up: a solar eclipse happens when the Moon passes between the Earth and Sun, blocking the Sun, while a lunar eclipse happens when the Earth comes between the Sun and Moon, casting its shadow on the Moon. Lunar eclipses are safe to watch, but never look at a solar eclipse without proper protection.

FAQ
what is the difference between a solar and lunar eclipse
A solar eclipse happens when the Moon passes between the Earth and the Sun, blocking the Sun from view. A lunar eclipse happens when the Earth passes between the Sun and Moon, casting its shadow onto the Moon. The alignment differs in each case.
are the descriptions accurate
Yes. Each eclipse type is paired with an accurate description of what causes it, so a total solar eclipse genuinely describes the Moon fully blocking the Sun. The pairings are reliable for study and teaching.
why does the Moon turn red in a lunar eclipse
During a total lunar eclipse, the only sunlight reaching the Moon has passed through Earth's atmosphere, which scatters blue light and lets red light through — the same effect that reddens sunsets. This gives the eclipsed Moon its coppery, blood-red glow.
