Orbital Mechanics & the Moon

[arobie]

Some of you know that I like to play Orbiter. Please forgive me for bringing up this game once again. <img src="/images/icons/smile.gif" /><br /><br />I've got a navigational question to those who can help me.<br /><br />The other day I started a flight to the Moon. I did my ejection burn from quarter of a million miles away and was actually too acurate for my tastes. As I appoached the Moon, I noticed that my vector velocity was smack dab in the middle of the Moon. Checking my Orbital displays, I notished that I was on a path to go straight through the center of the Moon.<br /><br />I figured that probably was not the best idea. I wanted to get into orbit so I could have a bit more say in my landing...or crash spot. I did an impromptu burn and pushed my vector velocity to what I thought was the east side of the Moon. Of course I also used my displays to make sure that I still wouldn't smash into the moon.<br /><br />After another burn, (to actually put me into Lunar orbit instead of the slingshot trajectory that I was in) I realized that I had actually entered Lunar orbit the opposite way that I had intended. Instead of orbiting from west to east, I was orbiting from east to west, opposite of the way spacecraft orbit around Earth. I thought this strange.<br /><br />Then I pulled up information about other satellites orbiting the Moon. They were orbiting the same way as I.<br /><br />So my question:<br /><br />Is it normal to orbit the Moon that way?
