Tárgy: Mars -2.9 at August 27th
The Red Planet is about to be spectacular! 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.
