    The period of a satellite in a circular orbit can be obtained by using the formula below:

    P = √ (4π²r³/GM)

    Where: constant GM of the Moon (gravity * mass) = 4.903x10^12 m³/s²

    Substituting and simplifying:

    P = 2.838x10^ (-6) * √ (1.738x10^6) ³

    P = 6502 seconds, or 108.37 minutes
