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 brighte r throughout the month.
