'''NGC 5634''' is a [[Astronomy:Globular cluster|globular cluster]] in the [[Astronomy:Constellation|constellation]] [[Astronomy:Virgo (constellation)|Virgo (constellation)]], located about 82,200 [[Light year|light year]]s (25.2 [[Astronomy:Parsec|kiloparsec]]s) away.<ref name=simbad/> NGC 5634 has an [[Astronomy:Apparent magnitude|apparent magnitude]] of about 10<ref name=simbad/> and a diameter of 4 or 5 arcminutes.<ref name=seds/> Its [[Shapley–Sawyer Concentration Class]] is IV,<ref name=hcob849_11/> meaning the cluster shows intermediate rich concentrations. The star near the upper right is the eleventh-magnitude UCAC2 29844847. There is also a bright orange giant, HD 127119, about 1.3 arcminutes away from the cluster.

NGC 5634 was once likely a member of the [[Astronomy:Sagittarius Dwarf Spheroidal Galaxy|Sagittarius Dwarf Spheroidal Galaxy]].<ref name=seds/> The galaxy itself is being pulled apart by tidal forces from the [[Astronomy:Milky Way|Milky Way]], similar to how NGC 5634 was pulled from the Dwarf Spheroidal Galaxy.
