    The eccentric formula for ellipse can be calculated using

    e = (r_a - r_p) / (r_a + r_p)

    r_a is the longest distance between the moon and its planet

    r_p=0.27 r_a is the shortest distance between the moon and its planet

    Then,

    e = (r_a - r_p) / (r_a + r_p)

    e = (r_a - 0.27 r_a) / (r_a + 0.27 r_a)

    e = 0.73r_a / 1.27 r_a

    e = 0.57

    This is the moon orbital eccentric
