This may be due to gravitational interaction between it and NGC 3729, another spiral galaxy located 150,000 light-years away.[7] NGC 3718 is a member of the Ursa Major Cluster.[8] References1. ^1 2 {{cite journal|title=The Two Micron All Sky Survey (2MASS)|author=Skrutskie, M.|display-authors=etal|journal=The Astronomical Journal|volume=131|issue=2|pages=1163–1183|year=2006|doi=10.1086/498708|bibcode=2006AJ....131.1163S}} {{galaxy-stub}}2. ^1 {{cite web|url=http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC+3718&extend=no&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|title=NED results for object NGC 3718|publisher=National Aeronautics and Space Administration / Infrared Processing and Analysis Center|accessdate=8 December 2017}} 3. ^1 2 3 {{cite simbad|title=NGC 3718|access-date=8 December 2017}} 4. ^{{Cite APOD|date=31 August 2006|title=Extra Galaxies}} 5. ^{{cite web|url=http://www.noao.edu/outreach/aop/observers/n3718.html|title=Best of AOP: NGC 3718|work=noao.edu}} 6. ^{{cite web|url=http://www.kopernik.org/images/archive/n3718.htm|title=NGC 3718, Spiral Galaxy|work=kopernik.org}} 7. ^http://apod.nasa.gov/apod/ap130803.html 8. ^{{Cite journal|last=Tully|first=R.
