What is the difference between apogee and perigee

This page on Apogee vs Perigee covers difference between apogee and perigee terms related to satellite. There are two main types of orbits in which satellite is placed for installation above the Earth.

The orbits are circular and elliptical. The satellite is used for wireless communication and it covers larger area of the earth.

The point of the orbit closest to Earth is called perigee, while the point farthest from Earth is known as apogee. As a result, the distance between the Moon and Earth varies throughout the month and the year.

On average, the distance is about , kilometers , miles from the Moon's center to the center of Earth. The point on the Moon's orbit closest to Earth is called the perigee and the point farthest away is the apogee.

Find the Moon's distance from your location. The Moon's phase and the date of its approach to its perigee or apogee are not synced. The Moon passes through the 2 extreme points—or apsides—perigee and apogee about once a month. The time it takes for the Moon to travel from perigee to perigee, is called the anomalistic month , and takes around In reality, a number of local and transient factors, such as the shape of the coastline, the flow of currents, and the weather, must also be taken into account.

Instructions Study the image to see how the distances between the Earth and the moon and sun change over the course of a month and a year, then answer the questions below. Orbital Shape The orbital paths of the moon around the earth and the earth around the sun are both elliptical.

Earth is at its maximum distance from the sun at aphelion, and at its minimum distance at perihelion. These orbits produce cyclical changes in the height of the tides. Lunar Day.
