    But the moon is so much smaller than Earth. Seems like a lot more would get through, unless there is some kind of pull.

    It was traveling 90,000 Kms per hour. Thats fast.

    unless the rock is traveling other than in an orbital path, the moon will usually get most of the debris. Only when a rock is not on an orbital path is there trouble.

    almost ALL the debris out there IS in an orbital path around the sun, as the earth/moon/Jupiter has been clearing out those that are not in an orbital path for billions of years.

    besides, 90kph is fast, about 3x faster than what is necessary for the escape velocity of a rocket leaving earth's gravitational tug.

    That is actually a big misconception. Although Jupiter protects Earth a lot more, the moon doesn't provide much protection. I believe the moon only reduces the amount of meteoroids from entering the Earth's atmosphere by about 10%. It is our own atmosphere that provides a lot of protection. The reason there are so many collisions on the moon is that it doesn't have an atmosphere to "burn" up the debris.

    not sure what the percentage is. but again, most of the debris that IS in an orbital path has already been cleared out already. those NOT on an orbital path are more likely to get through. MOST debris is in an orbital path

    Ah, I think I don't exactly understand what you are talking about then lol. May I ask for a source of your information, so I can better understand exactly what you are talking about? I think we are on different wavelengths, and I know what I am thinking about is correct.

    Also, "debris" is usually only used to describe man-made material. I was only talking about asteroids and meteoroids because that is what I thought JJ78 was talking about.
