## What it is
poliastro is a pure Python library for interactive astrodynamics and orbital mechanics, offering orbit propagation, maneuver planning, and quick visualization. It is now archived and no longer maintained, though forks are welcome.

## Use cases
- simulate satellite orbits in python
- compute orbital maneuvers like hohmann transfers
- plot spacecraft trajectories
- study orbital mechanics for a class
- convert between orbital elements and state vectors
- propagate keplerian orbits

## When to choose
- you need an easy-to-use Python library for orbital mechanics calculations
- you want quick orbit visualization in Jupyter notebooks
- you're doing academic work on astrodynamics and can accept an unmaintained dependency

## When to avoid
- you need long-term support or bug fixes, since the project is archived
- you need production-grade flight software
- you want an actively maintained alternative

## Facets
- artifact type: library
- maturity: abandoned
- function: simulation, data-visualization, math
- domain: simulation, astronomy, data-science, education
- platform: python, cross-platform
- tags: astrodynamics, orbital-mechanics, space, celestial-mechanics, orbits, scientific-computing, archived
