PROBLEM 1.8 A satellite is launched into earth orbit where its launch vehicle burns out at an altitude of 150 miles. So, perigee full Moons aren't all that unusual either, they occur every year. interval in days and hours. Using the mean lunar eccentricity provided in the same publication, one can calculate the following: - radius of the circular orbit of the mean apogee (Black Moon) around the Earth = 404,694 Km. The sign indicates The very closest Full Moons (within a few hours of perigee) recur with a cycle of 14 synodic months, because 14 synodic months nearly equals 15 anomalistic months.
