This month and next, Earth will catch up with Mars in an encounter that will culminate in the closest approach between the two planets in recorded history.
Due to the way Jupiter's gravity tugs on Mars and disturbs 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 next time Mars may come this close: 2287.
The encounter will culminate on August 27th when Mars comes to within 34,649,589 miles of Earth.
It 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.
To the naked eye Mars will look as large as the full moon!
Mars will be easy to spot. It will look as large as the full moon to the naked eye.
And by the beginning of August it will rise in the east at 10 p.m. and reach its azimuth at about 3 a.m.
Anyone into space and the planets? This sounds awesome.
