A solar eclipse occurs when the Moon passes between the Sun and Earth, casting a shadow on Earth. This can only happen during a new moon phase, when the Moon is positioned between the Sun and Earth.
The Moon’s orbit around Earth is tilted by about 5 degrees relative to Earth’s orbit around the Sun. This means that the Moon usually passes above or below the Sun in the sky. However, twice a year, the Moon’s orbit intersects Earth’s orbital plane. This is called a node. If the Moon is at a node during a new moon phase, it can cast a shadow on Earth, causing a solar eclipse.
There are four types of solar eclipses:
- Total solar eclipse: The Moon completely blocks the Sun. This type of eclipse is only visible from a narrow path on Earth, along the track of the Moon’s shadow.
- Annular solar eclipse: The Moon is too far away from Earth to completely block the Sun, leaving a ring of sunlight visible around the edge of the Moon.
- Partial solar eclipse: The Moon only partially blocks the Sun. This type of eclipse is visible from a much wider area than a total or annular eclipse.
- Hybrid solar eclipse: This is a rare type of eclipse that starts as an annular eclipse and ends as a total eclipse, or vice versa.
It is important to note that it is never safe to look directly at the Sun, even during a solar eclipse. Even a small amount of sunlight can damage your eyes. To safely view a solar eclipse, you must use special eclipse glasses or a solar filter.
Solar eclipses are fascinating astronomical events that offer a glimpse into the dynamic relationship between the Sun, Moon, and Earth.
