Average distance form earth=384,403,000 meters

  1. Apr 3, 2010 #1

    average distance form earth=384,403,000meters. Multiply by 2π=2,412,743,158meters
    orbital period=27days7hours43.1minutes=114,186sec

    This gives 2,412,743,158/114,186=21,130meters/sec linear speed.
    Wikipedia says 1,021meters/sec

    Where's the mistake?

    1 day is 86400 seconds, so 27 days can't be 114186 seconds.

    Cheers. Was hoping it was my mistake.
