For my uncle Zbys who watched the planets and stars.

Types and functions for dealing with Kepler orbits.

The main data type is Orbit, which describes the path of a body in orbit.

Symbol	Meaning	Notes
a	Semi-major axis	Negative for hyperbolic orbits
b	Semi-minor axis	Negative for hyperbolic orbits
e	Eccentricity
q	Periapsis
i	Inclination
μ	Standard gravitational parameter
Ω	Longitude of the ascending node
l	Semi-latus Rectum
n	Mean motion
p	Period
t	Time since periapse
M	Mean anomaly
E	Eccentric anomaly	Only for elliptic orbits
H	Hyperbolic anomaly	Only for hyperbolic orbits
ν	True anomaly
h	Specific angular momentum
ε	Specific orbital energy
εp	Specific potential energy
εk	Specific kinetic energy
v	Orbital speed or velocity
r	The radius to the orbiting body
φ	Flight path angle

Note that in the Haskell source uppercase symbols such as Ω and M are written with a leading underscore.

This package makes use of the units package to ensure that the implementation is correct regarding units of measure.
