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.[signature][hline]"I find your lack of faith disturbing."
