Sorry to have to post this, but it looked like an email I received some time ago. I went to
http://www.snopes.com and I copied this from the website. Here's the
direct link to the findings.
Mars Spectacular
Claim: The planet Mars will make a once-in-our-lifetimes remarkably close approach to Earth in August.
Status: Multiple:
Mars passed extraordinarily close to Earth in August 2003: True.
Mars will pass extraordinarily close to Earth in August 2006: False.
Example: [Collected on the Internet, 2003]
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 12:30 a.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. Share this with your children and grandchildren. NO ONE ALIVE TODAY WILL EVER SEE THIS AGAIN
Origins: The piece quoted above is another example of an item that was once true but is now being circulated again, long after the events it describes have come to pass. This article was relevant back in 2003, but it is not applicable now, three years later.
Mars did make an extraordinarily close approach to Earth which culminated on 27 August 2003, when the red planet came within 35 million miles (or 56 million kilometers) of Earth, its nearest approach to us in almost 60,000 years. At that time, Mars appeared approximately 6 times larger and 85 times brighter in the sky than it does ordinarily. (The message quoted above was often reproduced with an unfortunate line break in the middle of the second sentence of the second paragraph, leaving some readers with the mistaken impression that Mars would "look as large as the full moon to the naked eye" and not realizing that the statement only applied to those using viewing Mars through a scope with 75-power
magnification.)
Although Mars' proximity to Earth in August 2003 (referred to as a perihelic opposition) was a rare occurrence, the red planet comes almost as near to us every 15 to 17 years. To the unaided observer, Mars' appearance in August 2003 wasn't significantly larger or brighter than it is during those much more common intervals of closeness.
Mars had another close encounter with Earth in in 2005, but that occurrence took place in October (not August), and the red planet appeared about 20% smaller than it did during similar circumstances in 2003.
The Mars phenomenon of 2003 was featured in a couple of articles on the web site Space.com which are still well worth the reading: Mars to Get Closer than Ever in Recorded History in 2003 and Orbital Oddities: Why Mars will be So Close to Earth in August. Interested observers also joined Mars Watch 2003 through the MarsToday.com web site.
