The Astronomical Database is a database of astronomical entities. It currently contains data for 5742 entities.

Unlike most online astronomical databases, The Astronomical Database is mainly designed for physics and astronomy students, teachers, and enthusiasts, rather than academics. The emphasis of this site is ease-of-use, clear design, and data visualisation. The database updates automatically every day, but it can still be several weeks or months before new data or references for an entity appear on this site, and so it does not provide the most up-to-date data.
