Solstice:
The word means "sun stop." It refers to the two
moments each year when the sun appears to be farthest from the equator.
On the winter solstice in our hemisphere (around December 22), the
sun seems to reach its most southerly point. It is our shortest day
of the year. From there, it seems to head north until it reaches its
most northerly point. That is our summer solstice (around June 21):
the longest day of the year. When the Northern Hemisphere has its
summer solstice, the Southern Hemisphere has its winter solstice,
and vice versa.
The sun doesn't really move, but it looks like it does to
us. That's because our Earth is tilted as it revolves around the sun
once a year. |
