Lunar Eclipse Overview
A lunar eclipse occurs when the Earth passes between the Sun and the Moon, blocking sunlight from reaching the Moon. This celestial event can only happen during a full moon when the Sun, Earth, and Moon are aligned in a straight line.
Types of Lunar Eclipses
- Total Lunar Eclipse: The entire Moon passes through the Earth's umbra (the darkest part of its shadow), causing the Moon to appear red or coppery. This phenomenon is often referred to as a 'Blood Moon.'
- Partial Lunar Eclipse: Only a portion of the Moon enters the Earth's umbra, resulting in part of the Moon being darkened while the rest remains illuminated.
- Penumbral Lunar Eclipse: The Moon passes through the Earth's penumbra (the lighter part of its shadow). This type of eclipse is subtle and hard to notice, as the Moon only slightly darkens.
Phases of a Lunar Eclipse
- Umbra: The darkest part of the shadow, where all direct sunlight is blocked.
- Penumbral Shadow: The lighter outer part of the shadow, where only a portion of sunlight is obscured.
Viewing a Lunar Eclipse
- Lunar eclipses are safe to observe with the naked eye, unlike solar eclipses.
- The best time to view a lunar eclipse is during the total phase, which can last from a few minutes to several hours.
Frequency of Lunar Eclipses
- Lunar eclipses can occur anywhere from 2 to 7 times a year, but total lunar eclipses are less common.
Understanding lunar eclipses enhances appreciation for celestial mechanics and the beauty of the night sky.

Answer

A lunar eclipse is when the Earth's shadow falls on the moon, which can only happen during a full moon. This occurs when the Earth is between the sun and the moon, and all three celestial bodies are in the same orbital plane.

Here are some things to know about lunar eclipses:

When they happen
Lunar eclipses can occur two to five times a year, with at least two total lunar eclipses every three years.

How they look
During a lunar eclipse, the moon can appear red because the only sunlight reaching it passes through the Earth's atmosphere. The more dust or clouds in the atmosphere, the redder the moon will appear.

Why they're popular
Lunar eclipses are popular with skywatchers because they can be seen without special equipment.
