0 the point in the orbit (= curved path) of the moon or a satellite when it it is closest to the earth : --
It was operated in an orbit with a perigee of, an apogee of, 48.4 degrees of inclination, and an orbital period of 94.6 minutes.
The argument of perigee is such that apogee occurs on or near the equator.
Its orbit had a perigee of, an apogee of, 70 degrees of inclination, and an orbital period of 88.8 minutes.
It was operated in an orbit with a perigee of, an apogee of, 48.4 degrees of inclination, and an orbital period of 90.5 minutes.
The deorbit burn decelerated the orbiter by about 211 miles per hour, enough to lower its orbital perigee into the upper atmosphere.
An argument of perigee of 90 degrees would likewise serve the high southern latitudes.
This burn decreases the orbit's perigee to about 15 km, some 500 km ahead of the lunar south pole, half an orbit later.
It will be the fourth longest eclipse of the 21st century with a magnitude of 1.0774 occurring just one hour before perigee.
