Be sure to mark your calendar and remember to watch!!

MARK AUGUST 27th ON YOUR CALENDAR!

MARS WILL APPEAR AS BIG AS THE MOON!

FIRST TIME IN AT LEAST 5,000 YEARS!

Never again in your lifetime will the Red Planet (Mars) be so
spectacular!

This month and next, Earth is catching up with Mars, an encounter that
will culminate in the closest approach between the two planets in
recorded history. The next time Mars may come this close is in 2287. Due
to the way Jupiter's gravity tugs on Mars and perturbs its orbit,
astronomers can only be certain that Mars has not come this close to
Earth in the last 5,000 years but it may be as long as 60,000 years.

On August 27, Mars will come within 34,649,589 miles and will be (next
to the moon) the brightest object in the night sky. It will attain a
magnitude of -2.9 and will appear 25.11 arc seconds wide. At a modest
75-power magnification Mars will look as large as the full moon to the
naked eye. Mars will be easy to spot. At the beginning of August, Mars
will rise in the east at 10 p.m. and reach its azimuth at about 3 a.m.
But by the end of August when these two planets are closest, Mars will
rise at nightfall and reach its highest point in the sky at 12:30 a.m.
That's pretty convenient when it comes to seeing something that no human
has seen in recorded history.

So don't miss it---mark your calendar at the beginning of August to see
Mars grow progressively brighter throughout the month.

Share this with your friends, children and grandchildren. No one alive
today will ever see this again!!!
