What is a solar eclipse?
Eclipses happen when an object in space, such as a planet or Moon, passes through the shadow of another celestial body in space. On Earth, we can see the lunar and solar.
Solar occurs when the Moon is positioned between the Sun and the Earth, preventing light from reaching some points on our planet. Being in a place where it is total, it is possible to see the Moon blocking almost all the Sun's rays, making the day as dark as the night.
Total solar eclipses happen every 18 months and last a few minutes, while partial solar eclipses — in which the Moon does not completely cover the Sun — occur at least twice a year somewhere on Earth.
The phenomenon is classified into three types:
- Total solar eclipse: Visible only in a small area of ​​the Earth, when the person is in the center of the Moon's shadow, when it hits the Earth. For a total eclipse to occur, the Sun, Moon and Earth must be completely aligned.
- Partial solar eclipse: It happens when the Sun, Moon and Earth are not exactly aligned. The Sun appears to have a dark shadow on a small part of its surface.
- Annular solar eclipse: This is when the Moon is furthest from Earth and appears smaller. Because it does not block all view of the Sun, the Moon looks like a dark disk in front of the star.
- Hybrid solar eclipse: When there is more than one type of solar eclipse on the same day, it is the rarest type there is.
