    the oort cloud and kuiper belt...some questions

    i have some questions about the oort cloud and kuiper belt
    1. how much is the total mass of all the comets in the solar system?
    2. what is the average distance between the comets in the Oort Cloud?
    3. how far away is the kuiper belt?
    4. do all stars have oort clouds?
    5. what is the maximum speed of a comet as it comes around the sun?
    6. what would Chiron look like if it entered the inner solar system?
    7. what whould happen if Chiron hit the middle of the Atlantic Ocean?
    8. what would happen if Chiron hit the middle of the United States?
    8. could there be Kuiper Belt/Oort Cloud objects larger than Earth?
    9. what comet has had the longest orbital period?
    10. could we see a comet the size of Pluto be seen 10,000 A.U. away with the most powerful telescope on earth if we knew exactly where to look? if so, what would be its magnitude?
    11. to what distance does the oort cloud extend

    thanks a lot for your time

    1. how much is the total mass of all the comets in the solar system?
    Unknown. Probably on the order of one Earth mass. i.e. Between 0.1 and 10 M(e).
    2. what is the average distance between the comets in the Oort Cloud?
    Huge. Several A.U.
    3. how far away is the kuiper belt?
    30-100 A.U.
    4. do all stars have oort clouds?
    Unknown.
    5. what is the maximum speed of a comet as it comes around the sun?
    Approximately 600 kilometers/second (Same as the Sun's escape velocity.).
    6. what would Chiron look like if it entered the inner solar system?
    The mother of all comets.
    7. what whould happen if Chiron hit the middle of the Atlantic Ocean?
    We would all die.
    8. what would happen if Chiron hit the middle of the United States?
    See above.
    8. could there be Kuiper Belt/Oort Cloud objects larger than Earth?
    Probably not, or we would have seen it.
    9. what comet has had the longest orbital period?
    Some comets are one pass objects on parabolic or hyperbolic orbits. Their periods are infinite.
    10. could we see a comet the size of Pluto be seen 10,000 A.U. away with the most powerful telescope on earth if we knew exactly where to look? if so, what would be its magnitude?
    No.
    11. to what distance does the oort cloud extend.
    Unknown.

    thanks a lot for your time
