+# pystac-ext-ssys
+
+[PySTAC](https://pypi.org/project/pystac/) extension package for the [Solar System Extension](https://github.com/stac-extensions/ssys).
+This extension provides fields for describing the data of planetary bodies, including the target bodies, the local time and the target class of the body.
+
+## Supported versions
+
+- [v1.1.1](https://stac-extensions.github.io/ssys/v1.1.1/schema.json)
+
+## Versioning
+
+This package's version corresponds to the version of the extension specification it targets.
+When we release updates to the package code without changing the target extension version, we use [post releases](https://packaging.python.org/en/latest/discussions/versioning/#post-releases), e.g. `1.0.0.post1`.
