The Red Planet

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.


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