SIMBAD Astronomical Database - CDS (Strasbourg)

What is SIMBAD, and what is it not ?
The purpose of Simbad is to provide information on astronomical objects of interest which have been studied in scientific articles.

Simbad is a dynamic database, updated every working day.

It provides the bibliography, as well as available basic information such as the nature of the object, its coordinates, magnitudes, proper motions and parallax, velocity/redshift, size, spectral or morphological type, and the multitude of names (identifiers) given in the literature. The CDS team also performs cross-identifications based on the compatibility of several parameters, in the limit of a reasonably good astrometry.

Simbad is a meta-compilation built from what is published in the literature, and from our expertise on cross-identifications. By construction it is highly inhomogeneous as data come from any kind of instruments at all wavelenghts with any resolution and astrometry, and different names from one publication to another.

Simbad is not a catalogue, and should not be used as a catalogue. The CDS also provides the VizieR database which contains published lists of objects, as well as most very large surveys. The idea now is to use both Simbad and VizieR as completary research tools.

Content
The SIMBAD astronomical database provides basic data, cross-identifications, bibliography and measurements for astronomical objects outside the solar system.
SIMBAD can be queried by object name, coordinates and various criteria. Lists of objects and scripts can be submitted.
Links to some other on-line services are also provided.
Basic search
identifier, coordinates (radius=10 arcmin), or bibcode

SIMBAD on the Web is the WWW interface to the SIMBAD database. It offers the following functionalities:

Moreover, the interface provides links with many other data services :

SIMBAD on the Web has all the functionalities provided by XSimbad, after the addition of list queries in March 2001. XSimbad software is thus not maintained any more.
