> 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.
