One summer night in 2005 I was out on my roof with a couple of my friends, and the sky was perfectly clear. We could see thousands of stars, it was amazing. We were in the countryside far away from any city lights. Well, the entire night we were just star gazing and every 5 minutes we would see a "shooting star" (or that's what we thought at the time). The light would streak across the sky, so if you were looking directly up at the sky (90 degrees), the streaking lights would zip by from west to east. Is it possible to see at least 20 shooting stars in one night, or were the streaking lights in fact satellites? How often do satellites pass? How many satellites orbit the earth? Thanks.
