I'm doing a phd in chemistry <a href=" http://hidden-agenda.fr/germany-sex-drops-malaysia.pdf ">germany sex drops ebay</a> Let’s start with size. The Moon is about 2,000 miles in diameter. Mars is about twice as large, about 4,000 miles in diameter. The issue is the distance from Earth. The Moon is about 225,000 miles to 250,000 miles away from Earth, depending on the place in orbit. The closest Mars could ever get to Earth is about 34,000,000 (million) miles. So while Mars is twice as large, it is about 140 times farther away.
