1. Solar eclipses occur about twice a year. But seeing a total solar eclipse is often described as a "once in a lifetime" experience. Why is it so rare to experience a total solar eclipse?

• Total solar eclipses only occur once or twice a century.

• • The width of the Moon's shadow is very narrow, so a particular area is very unlikely to lie along the path of totality during the eclipse.

• Total solar eclipses usually occur in late winter, when clouds are most likely to block the view.

• • 
    If you aren't paying attention at the time, its very easy not to notice a total solar eclipse.

What is the best explanation for the frequency of eclipses?

• The Moon's orbit is tilted relative to the plane of the Earth's orbit. About every six months, the Sun, Moon and Earth are aligned enough for a solar and a lunar eclipse to occur.

• • 
    The Earth and Moon orbit the Sun in opposite directions. When the Moon's orbit crosses the Earth's orbit, a lunar or solar eclipse will occur.

• A lunar or a solar eclipse occurs every time the Moon orbits the Earth. The Moon orbits the Earth four times a year.

• The atmospheric conditions that cause eclipses are only found at certain locations and times of year.
