What is an annular solar eclipse? Why does it occur? .

An annular solar eclipse happens when the Moon covers the Sun's center, leaving the Sun's visible outer edges to form a "ring of fire" or annulus around the Moon. It happened because the apparent size of the Moon is smaller than that of the Sun

Approximately how many lunar and solar eclipses occur each year?

What causes the red color that may be visible during a lunar eclipse?

During a total lunar eclipse, the Earth moves between the Sun and the Moon and cuts off the Moon's light supply. When this happens, the surface of the Moon takes on a reddish glow instead of going completely dark.

Partial lunar eclipse?

Earth moves between the Sun and Moon but the three celestial bodies do not form a straight line in space. When that happens, a small part of the Moon's surface is covered by the darkest, central part of the Earth's shadow, called the umbra.

Are more people able to see a solar or a lunar eclipse? Why?
