spkezr is similar to
Spkpos, but computes the entire state vector.
Return the state (position and velocity) of a target body relative to an observing body, optionally corrected for light time (planetary aberration) and stellar aberration.

Units are Kilometers; Kilometers/Second.
A State Vector includes both a position (
r) and velocity term (
v). The full state vector is required for many operations, such as computing orbital elements.
