# sbpy Documentation¶

sbpy is an Astropy affiliated package for small-body planetary astronomy.

For an overview on the expected structure and functionality of sbpy, please refer to the About sbpy page; the Status Page page provides an overview on the implementation status of all modules and functions.

Important

sbpy is functional, but incomplete, and under heavy development. However, starting with the current stable version (v0.2), we expect most modules will have a stable API.

The development of sbpy is expected to conclude with version 1.0 in 2021.

## User Documentation¶
