About:
- A solar eclipse happens when the Moon passes in front of the Sun and casts a shadow across Earth. It's also known as an occultation.
Total solar eclipse:
- A total eclipse happens when the dark silhouette of the Moon completely covers the intense bright light of the Sun. Only the much fainter solar corona is visible during a total eclipse which is known as a Totality.
- Total solar eclipses are rare, happening only once every 18 months.
Comparison with Annular solar eclipse:
- This is when the Moon and the Sun are both exactly in line but either the Moon is further from Earth or the Earth is closer to the Sun.
- When this happens, the apparent size of the Moon is smaller than that of the Sun and the Sun then appears as a very bright ring, or annulus, surrounding the dark disk of the Moon.
