APFS HIP Simple Query

This service computes apparent and/or intermediate places of the stars in the Hipparcos main catalogue. Please note the warning on apparent places for multiple stars in the service info.

The positions can be given either in the CIO system (default) or the old equinox system.

If you give a position or an object resolvable by Simbad, the service will choose the nearest Hipparcos star for the ephemeris.

Enter a Hipparcos catalogue number, or a (decimal, comma-separated) position or simbad identifier to use the closest Hipparcos star.
