Solstice—December 21
-Our hours of daylight change each day of the
year
hours of darkness, too
Seasons change every ninety days or so and
vary life
for me and you
Long ago people thought the Sun circled our
Earth
once every night and day
If one watches it rise each morning, and
later set,
it certainly seems that way
So for most, Earth was the center of the
universe
but to some astronomers of old
The facts left a lot in the sky at night unexplained
and nudged the boys to be bold
In 1543 Copernicus published a book; it turned
the world upside down
He believed our Sun was the center of things…
many thought him a clown
But over time his thesis prevailed, and space
travel
has made it quite clear
Earth along with other planets do orbit a
stationary Sun
once each planet’s own “year”
Now this, our Earth, has three features
that affect us
the duration of our lives:
One daily rotation ‘round our N-S axis that
gives us daylight
plus the dark of night;
One trip around our Sun—as we rotate daily—that
takes
365 days plus a tad more it seems;
Through four different seasons during that trip…because
Earth’s N-S axis leans
Our axis leans away from the Sun’s N-S axis six
months
‘tween September and March each year
It then tilts back to the Sun’s axis to
complete the journey
home
again in September and glad to be here
In the center of each six months sits a
Solstice signaling
a zenith and a nadir
The zenith in sunny June marks the middle of
our summer,
the nadir December 21, our winter
Those in Australia on December 21 can surf and play
throughout the longest day
For folks in America or Russia—in the
Northern Hemisphere
it all works the opposite way.
