Lunar perigees and apogees occur during the orbit of the moon (or satellite) around the earth, hence monthly. For any given month, the time of each varies. Roughly each occur once during the month, (one perigee [when the moon is nearest to earth] and one apogee [farthest from earth]) given the orbit of the moon or lunar orbit.
Compare this with perihelion and aphelion having to do with the nearest and farthest orbit of a sphere around the sun, as the reply below addresses.
Curiously (for those of us in the northern hemisphere) Earth's perihelion (closest point of approach to the Sun) occurs in December.
"Perigee" means "closest point of approach to Earth" (peri=close, "gee" for the gravitation of earth), and is only used for things that orbit the Earth. I presumed that you were referring to the Earth's closest approach to the Sun, which is "perihelion". (Peri=close, Helios=the Greek god of the Sun).
What else can I help you with?
What exactly does perigee mean?
Perigee relates to the orbit of the moon. For example, perigee is defined as the moment when the moon is orbiting "closest" to the Earth. Apogee, the opposite of perigee, is when the moon is orbiting "farthest" away from the Earth.
What is a extreme perigee?
Perigee meaning close to Earth, it is when the moon comes at its closest; However because the orbit of the moon is elliptical and slightly eccentric, every 206 days the Moon comes 50,000 km closer than normal. This is its extreme perigee and gives the Illusion that is about 14% larger. The last one that occurred during a Full Moon prior to 2011 was in March 1993. These are also referred to a Super Moons.
What do you call the position of the moon if it is closest to the earth?
Perigee.
Does high tides occur when the moon is at perigee?
Yes
What is the opposite of apogee?
Perigee is the opposite of appogee. Perigee is the point in the orbit of the moon at which it is nearest to the earth. Apogee the point in the orbit of the moon at which it is furthest from the earth.
What exactly does perigee mean?
Perigee relates to the orbit of the moon. For example, perigee is defined as the moment when the moon is orbiting "closest" to the Earth. Apogee, the opposite of perigee, is when the moon is orbiting "farthest" away from the Earth.
Give you a sentence for perigee?
The astronomers were looking forward to the moon being at perigee. Now that the moon was at perigee, it was an ideal time to study it.
What is the real name of the super moon?

When does the moon reaches its perigee?
The perigee is the part of the Moon's orbit when the Moon is closest to the Earth. This happens once a month.
Will moon be at apogee or perigee on December 21 2010?
In December of 2010, the moon reaches apogee at 09 GMT on the 13th, and perigee at 12 GMT on the 25th.
Full moon perigee?
The closest the Moon gets to Earth is it perigee which is:-363,104 km225 622 Miles0.0024 AU
At what point is the moon closest to earth?
The point at which the Moon is closest to Earth is known as the perigee. This occurs approximately once a month when the Moon reaches its closest point to Earth in its elliptical orbit. This phenomenon is called a "perigee-syzygy."
How far is the earth from the moon at perigee At apogee?
its closer at perigee than at apogee.
What is the lunar perigee?
The side of the orbit of the moon that is closest to the Earth is the lunar perigee.
When the moon is closest to the earth it is at its what?
. . . perigee .
What is it called when the moon is bigger than usual?
a "perigee Moon,"
How often does a super moon happen?
They occur about once a year. Called perigee-syzygy or perigee moons by the astronomical community, they occur when a full or new moon (syzygy) is closest in its orbit to the earth (perigee), when the sun, earth and moon are aligned.
