«Mars will appear the size of the Moon…»
According to the information I know, 2003 was the first time that an email began to circulate on the Internet, with a PowerPoint presentation warning about a truly spectacular approach to Mars. Too spectacular. Some information provided in that presentation was correct, but others were totally false. The problem would have ended there, but this email circulated again in 2005 and again in 2006; Because the original powerpoint alluded to an event in 2003, and in the following years the only thing that was changed was the year, it can now be properly said that all the content of the powerpoint (which you can download here) it's false. Let's look at the facts:
Pseudoscience says...
Mars is about to make a spectacular appearance. Earth will reach Mars in an encounter that will culminate in the closest approach between the two planets that history has ever recorded; The next time Mars reaches a similar proximity will be in 2,287. Mars will be, after the Moon, the brightest object in the night skies... to the naked eye, Mars will look the size of the Moon! Share this information with your children and grandchildren, BECAUSE NO LIVING BEING TODAY WILL HAVE THE OPPORTUNITY TO SEE THIS PHENOMENON AGAIN!
Science says...
First of all, an initial clarification: approaches do exist, although their formal name is opposition. This is the name given to a moment when two stars are at points in the sky diametrically opposite to the Earth. One of these stars is the Sun, and the other can only be an external planet or the Moon; At that time, the star in opposition to the Sun is visible throughout the night and reaches its maximum apparent diameter in the sky, making it an excellent opportunity to observe them. If the opposition occurs during the star's perihelion (moment of closest proximity to the Sun), the observation will be very favorable; If it occurs during the star's aphelion (moment of greatest distance from the Sun), the observation will be very unfavorable.
