quote for the day

"If Earth were size of a school-room globe, you'd find Shuttle and Space Station orbiting 3/8th of an inch above its surface - the Moon would be 30-ft away (and) Mars, more than a mile away."

Neil deGrasse Tyson

Here's a really simple model showing the relationship between the earth and the moon.
