a total solar eclipse will across the
United States and people are really
excited that's because many Americans
have never seen a total solar eclipse
but why is that after all you only need
three things to make a solar eclipse the
Sun the earth and the moon in between
the moon passes between the Earth and
the Sun every 27 days so why don't we
get an eclipse every month
well solar eclipses only happen when the
moon's shadow falls on earth and most
months that shadow misses us it's all
due to the science of orbital mechanics
see the Earth revolves around the Sun in
this plane the moon revolves around the
earth in this plane which is five
degrees tilted the moon's shadow only
lands on us when the Moon and the
Earth's Plains line up making the Sun
Earth and Moon all align eclipses happen
every year but you still might not get a
total solar eclipse most commonly a
partial solar eclipse occurs where the
moon covers only part of the Sun and
about one third of solar eclipses are
annular they happen when the moon's
orbit takes it slightly farther away
from the earth the outer edges of the
Sun are exposed producing a glowing ring
around the moon total solar eclipses
only happened when the moon is close
enough to the earth to block out the
entire Sun that means around every 18
months there is a total solar eclipse
somewhere on earth luckily for us a
total solar eclipse is happening across
the United States from Oregon to South
Carolina along this path it's the first
one in 99 years to go all the way across
America so hope for clear skies and
don't forget your ISO approved eclipse
