NGC 332 is a compact and likely lenticular galaxy located in the constellation Pisces. Situated at a Right Ascension of 00h 59m 03.9s and a Declination of +29° 22' 40", this celestial object was first recorded on October 22, 1886, by the prolific American astronomer Lewis Swift[2] [1, 2]. While its formal classification as lenticular (S0) places it as an intermediate between a spiral and an elliptical galaxy, its compact nature is a defining characteristic, making it appear small and dense from our perspective.

Modern astronomical observations have provided a clearer picture of this galaxy's properties. NGC 332 is estimated to have an apparent magnitude of approximately 14.5 and a physical diameter of roughly 28,000 light-years [3, 4]. It is located at a distance of about 260 million light-years (80 megaparsecs) from Earth, placing it firmly within the local universe but not as a close neighbor [3]. While it is a member of the Pisces-Perseus Supercluster, it appears to be a relatively isolated galaxy, not part of a close-knit group, which is of interest to astronomers studying galaxy evolution and formation in different environments [5].

The galaxy's initial description by John Louis Emil Dreyer in his seminal New General Catalogue (NGC) captures the challenges of 19th-century observational astronomy. Dreyer described it as "very faint, small, round, several stars near to south," a description that accurately reflects its faintness as seen through the telescopes of that era [6]. The "several stars near to south" were likely a mere optical coincidence in the field of view, now confirmed by modern imaging to be foreground stars in our own galaxy, rather than a physical part of NGC 332 [5]. The study of such galaxies continues to provide valuable insights into the Hubble sequence and the processes that lead to the formation of different galactic types.
