When a full moon phase and a perigee (or near perigee) place in its orbit coincide, we call that a super moon," Raymundo explained.
That causes the moon to appear much bigger and brighter in our sky than usual, and it's referred to as a supermoon - or more technically, a perigee moon.
It is probable that full moon on November 4 and December 3 (with perigee), new moon on November 18 and December 18 and lunar perigee on November 6 will bring stronger-than-average storms to the United States.
But over those 27 days the Earth has moved round the sun a bit, so the moon has to "catch up" over the course of a couple of days to get back to being opposite the sun, by which point it's not at perigee anymore.
When a Earth-Moon-Sun alignment occurs with the perigee side of the Moon facing Earth, and the Moon is on the opposite side of the Earth from the Sun, we get a perigee-syzygy.
Supermoons, or perigee full-moons, occur when a new or full moon makes the closest approach to the Earth on its elliptical orbit.
In the earliest phase, the "rendezvous" took place at the perigee point of the interceptor where latter was detonated on command.
Fajr's perigee (low point) is not dropping as quickly.
The satellite has been put into an orbit having a Perigee or nearest point to the Earth at 32,160 km and apogee or farthest point to the Earth at 35,745 km, with an inclination of 0.
Also known as a Perigee moon, it occurs every 14 full moons, when the oval orbit of earth's satellite brings it 28,000 miles closer than usual.
The orbit is slightly elliptical and so the moon has far points and near points, which we astronomers call its apogee and perigee.
Summary: SHARJAH -- The moon will be on its perigee, or the closest approach to the earth, on June 3 and the biggest and the brightest "super moon" will be born at sunset on June 4, researchers said.
