  A trending astronomical phenomenon to study is the variation in brightness of
asteroids, caused by its rotation on its own axis, non-spherical shapes,
changes of albedo along its surface and its position relative to the sun. The
latter behaviour can be visualized on a "Phase Curve" (phase angle vs. reduced
magnitude). To enable the comparison between several models proposed for this
curve we present a Python package called Pyedra. Pyedra implements three
phase-curve-models, and also providing capabilities for visualization as well
as integration with external datasets. The package is fully documented and
tested following a strict quality-assurance workflow, with a user-friendly
programmatic interface. In future versions, we will include more models, and
additional estimation of quantities derived from parameters like diameter, and
types of albedo; as well as enabling correlation of information of physical and
orbital parameters.
