Description

**poliastro** is an open source collection of Python subroutines useful in Astrodynamics and Orbital Mechanics. It tries to provide a simple and intuitive API and handles physical quantities with units. Some of its awesome features are: * Orbit propagation (Keplerian orbits) * Conversion between position and velocity vectors and classical orbital elements * Hohmann and bielliptic maneuvers computation * Trajectory plotting * Initial orbit determination (Lambert problem) * Planetary ephemerides (SPICE kernels) And more to come!
