exoatlas: Friendly Python Code For Exoplanet Populations

Example exoatlas visualization placing the first discovered transiting exoplanet HD209458b in context with other transiting exoplanets and the eight major Solar System planets. Errorbars use a color intensity that scales inversely with quantity uncertainties, to avoid giving undue visual weight to the least precise data. β€” astro-ph.IM

Planets are complicated. Understanding how they work requires connecting individual objects to the context of broader populations.

Exoplanets are easier to picture next to their closest Solar System archetypes, and planets in the Solar System are richer when seen alongside a growing community of known exoplanets in the Milky Way.

The exoatlas toolkit provides a friendly Python interface for retrieving and working with populations of planets, aiming to simplify the process of placing worlds in context.
