Eclipse happens once in years, here are reasons

Few days ago, the world experienced eclipse in some parts of the earth. The last time I witnessed an eclipse was in 2006. Wow! Eclipse happens once in many years and for many reasons:

Alignment of Sun, Moon, and Earth: Eclipses occur when the Sun, Moon, and Earth align. A solar eclipse happens when the Moon passes between the Sun and Earth, casting a shadow on Earth.

New Moon Phase: Solar eclipses occur during the new moon phase when the Moon aligns itself to eclipse the Sun, blocking its light from reaching Earth.

Perfect Sizing: The Moon and Sun appear the same size in the sky due to cosmic coincidence; the Moon is about 400 times smaller than the Sun but also about 400 times farther away, allowing for a perfect alignment during a solar eclipse.

Umbra and Penumbra Shadows: During a solar eclipse, the Moon casts two shadows on Earth: the umbra, the dark center where a total eclipse is visible, and the penumbra, where a partial eclipse can be seen.

Occultation: Total solar eclipses are technically occultations of the Sun by the Moon, occurring when the Moon moves in front of the Sun and blocks out most of its light, creating the phenomenon observed during an eclipse.
