Calculation
The eccentricity vector can be calculated
where:
- is orbital velocity vector,
- is orbital angular momentum vector,
- is orbital position vector,
- is standard gravitational parameter.
or equivalently from the orbital state vectors by
where:
- is velocity vector of the orbital state vectors,
- is position vector of the orbital state vectors,
- is standard gravitational parameter.

Famous quotes containing the word calculation:
““To my thinking” boomed the Professor, begging the question as usual, “the greatest triumph of the human mind was the calculation of Neptune from the observed vagaries of the orbit of Uranus.”
“And yours,” said the P.B.”
—Samuel Beckett (1906–1989)
“Common sense is the measure of the possible; it is composed of experience and prevision; it is calculation appled to life.”
—Henri-Frédéric Amiel (1821–1881)
