NGC 6229 is a globular cluster located in the constellation Hercules. It is designated as GC(v)B in the galaxy morphological classification scheme and was discovered by the British astronomer William Herschel on 12 May 1787. NGC 6229 is located at about 100,000 light years away from Earth.{{cite web|title=Object No. 1 – NGC 6229|url=http://ned.ipac.caltech.edu/cgi-bin/objsearch?objname=NGC+6229&extend=no&hconst=73&omegam=0.27&omegav=0.73&corr_z=1&out_csys=Equatorial&out_equinox=J2000.0&obj_sort=RA+or+Longitude&of=pre_text&zv_breaker=30000.0&list_limit=5&img_stamp=YES|website=NASA/IPAC extragalactic database|publisher=NASA/IPAC|access-date=3 October 2015}}{{cite web|title=Revised NGC Data for NGC 6229|url=http://spider.seds.org/ngc/revngcic.cgi?NGC6229|website=Seds|access-date=3 October 2015}}{{cite web|title=NGC NGC 6229 (= GCL 47)|url=http://cseligman.com/text/atlas/ngc62.htm#6229|website=cseligman|access-date=3 October 2015}}{{cite web|title=NGC 6229|url=http://www.ngcicproject.org/ngcicdb.asp|website=NGC/IC Project|access-date=3 October 2015|url-status=dead|archive-url=https://web.archive.org/web/20120520010558/http://www.ngcicproject.org/ngcicdb.asp|archive-date=20 May 2012}}

It is an intermediate-metallicity globular cluster with two distinct generations of stars, and may be the remnant core of a spheroidal dwarf galaxy.
