description={two-line element set 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 prediction formula, the state (position and velocity) at any point in the past or future can be estimated to some accuracy. TLEs can describe the trajectories only of Earth-orbiting objects. TLEs are widely used as input for projecting the future orbital tracks of space debris for purposes of characterizing ``future debris events to support risk analysis, close approach analysis, collision avoidance maneuvering'' and forensic analysis. The format was originally intended for punched cards, encoding a set of elements on two standard 80-column cards%
