Lunar and Solar Eclipses

Rooks, Cameron, Nevin & Brent

What are Eclipses

An obscuring of the light from one celestial body by the passage of another between it and the observer or between it and its source of illumination. There are two types of Eclipses, a Lunar and Solar, and both of which have 3 types of Eclipses: Total, Partial and Penumbral.


Total Eclipse-when one celestial body completely covers the other celestial body

Partial Eclipse-when the celestial body partially covers the other celestial body

Penumbral Eclipse-when the moon becomes completely immersed in the penumbral shadow cone of the Earth without touching the main umbra shadow.

Annular Eclipse-an eclipse of the sun in which the edge of the sun remains visible as a bright ring around the moon.

Lunar Eclipse

A lunar eclipse occurs when the moon appears darkened as it passes into the earth's shadow. This happens anywhere around 2-4 times per year depending on the year.


Why does the moon turn red during a lunar eclipse? The Earth's atmosphere provides an orangish color to the moon during an eclipse. The atmosphere acts like a filtered lens. It bends red sunlight into our planet's shadow and scatters out blue light. It's the same reason why sunrises and sunsets appear reddish.

A partial lunar eclipse occurs when only part of the moons surface is obscured by the Earth's Umbra

Solar Eclipse

A solar eclipse occurs when the moon gets between Earth and the sun, and the moon casts a shadow over Earth. A solar eclipse can only take place at the phase of new moon, when the moon passes directly between the Sun and Earth, and its shadows fall upon Earth’s surface. Only lasts about 7.5 minutes on any one location.
