Got an email today that included the following information for those who are interested:
“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 magni-
tude 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 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.”
There is a spectacular photo at cnn.com under the “Space Chronicles” story.
Nifty!
