A Martian Urban Legend

   It’s back!
   A friend asked about this picture and from the text on the graphic I am assuming that this is the Internet Urban Legend that comes back around this time of the year. This is the suggestion that Mars will be so close to the Earth that it will appear as large as the full Moon. Nothing of the sort will happen. This idea probably got its start from August 2003 when Mars was at opposition very close to the time it was at perihelion, closest to the Sun, while the Earth was at aphelion, its most distant from the Sun. This combination brought the Earth and Mars to about as close as they ever could be.

   For the record the Moon on August 27th is in the waxing gibbous phase, 2 days before full Moon, and it rises about 2 hours before sunset. Mars, on the other hand, rises about 2 hours before sunrise with the much brighter Venus nearby.

    I posted a blog about this previously, as well as wrote one of my Scope on the Sky columns about this suggestion.
