> CLOSE ENCOUNTER WITH MARS
>
> 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.
>
> The encounter will culminate on August 27th when Mars comes to 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 he 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 the
> 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, mark your calendar at the beginning of August to see Mars grow
> progressively brighter and brighter throughout the month.

> Share this!

> No one alive today will ever see this again.
