Perigee

Perigee is a term used to describe the closest point at which an object orbits the Earth or another object in space. When an object is at its perigee, it travels faster than it does at any other point in its orbit because it is under the influence of the strongest gravitational force that its source gives, which propels it further in its orbital path. How Perigee Works Although there are several different types of orbits that an object can take around its source, most objects travel in an elliptical path because it must first escape the source’s gravitational force.
