HD 218566 is a star in the equatorial zodiac constellation of Pisces. It has the proper name Ebla, after a kingdom in ancient Syria. With an apparent visual magnitude of 8.6,[2] this ninth magnitude star can not be viewed with the naked eye. However, it can be readily seen even with a small telescope.[9] It is located at a distance of 94 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −37.8 km/s.[4] The star hosts one known exoplanet, HD 218566 b.[2]
