At an estimated 140,000 light-years in diameter,<ref name="cseligman" /> NGC 1 is roughly the same size as our galaxy, the [[Milky Way]], which is believed to be approximately 160,000 light-years across.<ref>{{Cite news|url=https://www.space.com/29270-milky-way-size-larger-than-thought.html|title=Size of the Milky Way Upgraded, Solving Galaxy Puzzle|work=Space.com|access-date=2017-11-12}}</ref> Although its [[apparent magnitude]] of 13.65 makes the galaxy appear too faint to see with the naked eye, its [[absolute magnitude]] of -22.08 makes NGC 1 two to three times more [[Luminosity|luminous]] than our home galaxy. The galaxy is 4.0 Mly away from the 80,000 light-years wide galaxy [[UGC 69]], its nearest major neighbor.

NGC 1 has a visual size of 1.6' × 1.2'.<ref name="ned" /> Being [[Galaxy morphological classification|classified]] as a SABbc class galaxy using the [[Hubble sequence]] and the [[De Vaucouleurs system]] as an extension, NGC 1 is a spiral galaxy with the presence of a weak [[Barred spiral galaxy|nuclear bar]] and loosely wound arms.<ref name="Class">{{cite journal|last=de Vaucouleurs|first=Gérard|title=Revised Classification of 1500 Bright Galaxies|journal=Astrophysical Journal Supplement|date=April 1963|volume=8|page=31|doi=10.1086/190084|bibcode = 1963ApJS....8...31D }}</ref>  Although the central galaxy is only about 90,000 light-years across, a large, diffuse arm extends eastwards from it, possibly from a past merger.

Based on its [[redshift]] of approximately 0.015177 and thus [[recessional velocity]] of 4450&nbsp;km/s,<ref name="ned" /> the distance of the galaxy from the Solar System can be calculated using [[Hubble's law]]. Using current observation data, this places the galaxy at approximately 210 to 215 million light-years from Earth, which is in good agreement with redshift-independent distance estimates of 175 to 245 million light years. An opposing measurement of the galaxy's recessional velocity of 2215&nbsp;km/s would place the galaxy only about 100 million light-years away. However, this is regarded unlikely by most astronomers and believed to be a misattributed value for a different galaxy.<ref name="cseligman" />
