It was discovered in 1785 by William Herschel. NGC 450 has a very close companion, UGC 807 (or PGC 4545), which is attached at the northeast side of the halo. UGC 807 appears fairly faint, fairly small, and elongated. Despite the fact that UGC 807 appears to form a double system, the companion has a redshift that is over six times greater than NGC 450, so they are a line-of-sight pair.[2]{{Gallery |title=NGC 450 |align=center |File:NGC 0450 2MASS.jpg |Photo taken by 2MASS |File:NGC 0450 SDSS.jpg |Photo of NGC 450 and PGC 4545 taken by SDSS. }} References1. ^1 2 3 {{cite web | title=NASA/IPAC Extragalactic Database | work=Results for NGC 0450 | url=http://nedwww.ipac.caltech.edu/cgi-bin/nph-objsearch?objname=NGC+450&img_stamp=yes&extend=no | accessdate=2017-04-26}} 2. ^1 2 {{cite web|url=http://www.ngcicproject.org/NGC/NGC_4xx/NGC_450.htm|title=NGC/IC Project Restoration Effort|work=NGC450|accessdate=2017-04-26}} External links{{WikiSky}}{{Ngc5}}{{Catalogs|NGC=450|PGC=4540|UGC=806}}{{galaxy stub}}{{DEFAULTSORT:NGC 450}} 5 : Galaxies discovered in 1785|Cetus (constellation)|NGC objects|UGC objects|Principal Galaxies Catalogue objects |
