poliastro is an open source (MIT) pure Python library for interactive Astrodynamics and Orbital Mechanics, with a focus on ease of use, speed, and quick visualization. It provides a simple and intuitive API, and handles physical quantities with units.
Some features include orbit propagation, solution of the Lambert's problem, conversion between position and velocity vectors and classical orbital elements and orbit plotting, among others. It focuses on interplanetary applications, but can also be used to analyze artificial satellites in Low-Earth Orbit (LEO).
from poliastro.examples import molniya
molniya.plot()
Complete documentation, including a user guide and an API reference, can be read on the wonderful Read the Docs.
In the examples directory you can find several Jupyter notebooks with specific applications of poliastro. You can launch a cloud Jupyter server using binder to edit the notebooks without installing anything. Try it out!

poliastro requires the following Python packages:
- NumPy, for basic numerical routines
- Astropy, for physical units and time handling
- numba, for accelerating the code
- jplephem, for the planetary ephemerides using SPICE kernels
- matplotlib, for orbit plotting
- plotly, for 2D and 3D interactive orbit plotting
- SciPy, for root finding and numerical propagation
poliastro is supported on Linux, macOS and Windows on Python 3.8 to 3.10.
The easiest and fastest way to get the package up and running is to install poliastro using conda:
$ conda install poliastro --channel conda-forgePlease check out the documentation for alternative installation methods.

poliastro comes from Polimi, which is the shortened name of the Politecnico di Milano, the Italian university where I was studying while writing this software. It's my tiny tribute to a place I came to love. Grazie mille!
Yes! poliastro is a community project that strives to be easy to use, while at the same time producing correct results that are validated against other commonly used Astrodynamics software such as GMAT and Orekit.
Sure, we encourage you to open an issue so we can discuss future feature additions!
poliastro is actively maintained and receiving an influx of new contributors thanks to the generous sponsorship of Google and the European Space Agency. The best way to get an idea of the roadmap is to see the Milestones of the project.
