Understanding What a Solar Eclipse Is
A solar eclipse happens when the Moon moves between the Earth and the Sun. The Moon blocks sunlight and casts a shadow on parts of Earth, creating a brief dimming of the day.
How a Solar Eclipse Forms
For an eclipse to occur, the Sun, Moon, and Earth must line up perfectly. This alignment is rare because the Moon’s orbit is slightly tilted, so it usually passes above or below the Sun.
Types of Solar Eclipses
There are three main types: total, partial, and annular. In a total eclipse, the Moon fully covers the Sun. In a partial one, only part of the Sun is blocked. In an annular eclipse, a bright ring remains visible.
Why Solar Eclipses Don’t Happen Often
Even though the Moon orbits Earth every month, perfect alignment requires precise positioning. This makes solar eclipses special and relatively uncommon.
The Simple Takeaway
A solar eclipse occurs when the Moon blocks the Sun and casts a shadow on Earth. It’s a rare alignment that briefly changes daylight into an unusual and stunning sight.
