This month the 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 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.

Mars will look as large as the full moon to the naked eye.

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.

Mars / Earth Catching Up

The Red Planet is about to be spectacular!
This page is an example of how easily erroneous information can be so easily distributed in our modern world of instant technology.  We thank Rev. John Clifford for the following:

Not sure if this is a spoof or just a couple years behind the times.... The very near
approach of Mars is certainly not this year.  But what is meant by the line that Mars
will appear as large as the Moon to the naked eye???  Nonsense!
