Orbital elements are the parameters required to uniquely identify a specific orbit. In celestial mechanics these elements are considered in two-body systems...

The proper orbital elements or proper elements of an orbit are constants of motion of an object in space that remain practically unchanged over an astronomically...

In celestial mechanics, an orbit (also known as orbital revolution) is the curved trajectory of an object such as the trajectory of a planet around a star...

three-line element set (3LE) is a data format encoding a list of orbital elements of an Earth-orbiting object for a given point in time, the epoch. Using a suitable...

osculating orbit and the object's position upon it can be fully described by the six standard Kepler orbital elements (osculating elements), which are...
