NGC 7329 is a large barred spiral galaxy located in the constellation Tucana.{{Cite web |title=By Name {{!}} NASA/IPAC Extragalactic Database |url=https://ned.ipac.caltech.edu/byname?objname=NGC+7329&hconst=67.8&omegam=0.308&omegav=0.692&wmap=4&corr_z=1 |access-date=2024-03-22 |website=ned.ipac.caltech.edu}} NGC 7329 was discovered by British astronomer John Herschel in 1835.{{Cite web |url=https://astrovalleyfield.ca/AstronomieCompl/NGC%20et%20autres/WolfgangS/N7300_exc_web.htm |title=Natural Sciences program at the Cégep of Valleyfield |access-date=2024-03-22 |website=astrovalleyfield.ca}}
The luminosity class of NGC 7329 is II and it has a broad HI line. To date, 29 non-redshift measurements yield a distance of 44.662 ± 5.536 Mpc (~146 million ly),{{Cite web |title=NED Query Results for NGC 7329 |url=https://ned.ipac.caltech.edu/cgi-bin/nDistance?name=NGC+7329 |access-date=2024-03-22 |website=ned.ipac.caltech.edu}} which is within the Hubble distance range. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy.{{Cite web |title=SN 2006bh {{!}} Transient Name Server |url=https://www.wis-tns.org/object/2006bh |access-date=2024-03-22 |website=www.wis-tns.org}}
Discovery
This galaxy was discovered in 1835 by the English astronomer John Herschel using a 47.5 cm (18.7 in) optical telescope that used a mirror as the light-gathering element.
