SkyServer Database Documentation

These pages give you access to documentation for all the data stored in the SkyServer database. These documents tell you what each data type means. You will need to know the data types to write SQL queries to search through the data.

  • The Object Browser will let you navigate interactively among the contents and descriptions of the different tables.
  • The Glossary provides a one paragraph explanation of the most important terms appearing in the documentation.
