Subject: MARS -The Red Planet


The Red Planet is about to be spectacular! This month and next, Earth is
catching up with Mars in 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 before it happens
again.

The encounter will culminate on August 27th when Mars comes to within
34,649,589 miles of Earth 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 it will rise in the east at 10p.m. and reach its
azimuth at about 3 a.m.

By the end of August when the two planets are closest, Mars will rise at
nightfall and reach its highest point in the sky at 12:30a.m. That's pretty
convenient to see something that no human being has seen in recorded
history. So, mark your calendar at the beginning of August to see Mars grow
progressively brighter and brighter throughout the month. Share this with
your children and grandchildren. NO ONE ALIVE TODAY WILL EVER SEE THIS
AGAIN

Mars' closest approach , 27.8.2003 NZST. may be auspicious as the

closest approach of bright planet Mars to Earth for approx. 60,000
years claimed.

i saw through carter observatory telescope, wellington, new zealand.
mars' white polar ice cap and, diametrically opposite, a star nearly
occulted (1 mars x diameter beyond the circle of disk.)

in early 17th century, Johannes Kepler published 3 laws of planetary
motion.
of course date 27.8.2003, month 8 is 2 cubed = 2*2*2, and day 27 is 3
cubed.

kepler's third law defines the relations that hold within the system
of planets. it states that the ratio between the square of a planet's
period (the time to complete 1 orbit) to the cube of the mean radius
(the average distance from the Sun during 1 orbit -- query semimajor
axis of ellipse) is a constant.
McGraw-Hill Encyclopedia of Science and Technology, 3 edn.

Therefore, example date, if 27 years (or 8 years) is the period, then
3-squared = 9 (or 2-squared equals 4, respectively) would be the mean
radius in Astronomical Units (1 A.U. = Earth-Sun distance.)

Hence also, the 'inside runner Earth overtakes' the outer planet,
Mars. Two circles does not show this quite as well as a sequence of
line segments joining a moving point in 1 orbit to the second planet
at corresponding time in the other. ! / -.
