perigee

(pĕr`ĭjē), point nearest the earth in the orbit of a body about the earth. See apsisapsis
(pl. apsides), point in the orbit of a body where the body is neither approaching nor receding from another body about which it revolves. Any elliptical orbit has two apsides.

perigee

(pe -ră-jee) The point in the orbit of the Moon or an artificial Earth satellite that is nearest the Earth and at which the body's velocity is maximal. Strictly, the distance to the perigee is taken from the Earth's center. The distance to the Moon's perigee varies; on average it is about 363 300 km. Compare apogee.

Perigee

(religion, spiritualism, and occult)

Every orbit is elliptical. When a satellite is closest to Earth, it is at its perigee (from the Greek peri, meaning “near,” and gaia, meaning “earth”).

Perigee

 

the point in the orbit of the moon or an artificial satellite that is nearest the earth. Perturbations change the position of the perigee in space. Thus, because of perturbations caused by the sun, the moon’s perigee moves along an orbit in the same direction as the moon, completing a revolution in 8.85 years. The shift in the perigee of an artificial earth satellite chiefly arises from the aspherical nature of the earth, and the magnitude and direction of this motion depend on the inclination of the orbital plane of the satellite to the plane of the earth’s equator. The distance from the perigee to the center of the earth is called the perigee distance.

It should be noted that the Moon average distance from us, approximately 384,000km and it gets close to the perigee every lunar month but this time is closer than usual by more than ten thousand kilometres, although not the closest of all time as this phenomena repeat every 18 years and therefore there is no need to panic and fear.
According to Tanyu Bonev the Saturday's phenomenon is interesting because the lunar perigee coincides with full moon, which means that the Sun, the Earth and the Moon will be almost aligned.
The distance at perigee and apogee are given by the equations below:

Its perigee (the point of its closest approach to the Earth) moved somewhat with each revolution, in part because of the gravitational pull of the Earth's equatorial bulge upon it.
But, this pragmatism aside, most Fellows (64 percent) see the mega-agencies approaching their perigee, ultimately self-destructing and giving rise to smaller, entrepreneurial units.
It will appear brighter and bigger than a usual full moon because it will be closer to the time of perigee.
Supermoons refer to a full moon that appears roughly at the same time of the point of the lunar orbit that is closest to Earth, known as perigee.
The term Supermoon entered usage five years ago but the scientific term is perigee full moon.
