What is a Lunar Eclipse?

Back

A Lunar Eclipse occurs when the Earth passes between the Sun and the Moon, causing the Earth's shadow to fall on the Moon.

Front

What are the three types of Lunar Eclipses?

Back

The three types of Lunar Eclipses are Total Lunar Eclipse, Partial Lunar Eclipse, and Penumbral Lunar Eclipse.

Front

What is a Penumbral Lunar Eclipse?

Back

A Penumbral Lunar Eclipse occurs when the Moon passes through the Earth's penumbral shadow, resulting in a subtle shading on the Moon's surface.

Front

What is the Penumbra?

Back

The Penumbra is the outer part of a shadow where light is partially blocked, creating a gradient effect.

Front

What safety measures should be taken when viewing a Solar Eclipse?

Back

Protective eyewear, such as eclipse glasses or solar viewers, should be used to prevent eye damage when viewing a Solar Eclipse.

Front

What is the difference between a Total Solar Eclipse and a Partial Solar Eclipse?

Back

A Total Solar Eclipse occurs when the Moon completely covers the Sun, while a Partial Solar Eclipse occurs when only a part of the Sun is obscured by the Moon.

Front

What causes the different phases of a Lunar Eclipse?

Back

The different phases of a Lunar Eclipse are caused by the alignment of the Earth, Moon, and Sun, which determines how much of the Moon is covered by the Earth's shadow.

Front

How often do Solar Eclipses occur?

Back

Solar Eclipses occur approximately 2 to 5 times a year, but total Solar Eclipses at any specific location are rare.
