IC 5332, also known as PGC 71775, is an intermediate
spiral galaxy
Spiral galaxies form a galaxy morphological classification, class of galaxy originally described by Edwin Hubble in his 1936 work ''The Realm of the Nebulae'' about 30 million
light-years
A light-year, alternatively spelled light year (ly or lyr), is a unit of length used to express astronomical distances and is equal to exactly , which is approximately 9.46 trillion km or 5.88 trillion mi. As defined by the International Astro ...

. It was discovered by American astronomer Lewis Swift
Lewis A. Swift (February 29, 1820 – January 5, 1913) was an American astronomer who discovered 13 comets and 1,248 previously uncatalogued nebulae. Only William Herschel discovered more nebulae visually.

IC 5332 is a late type spiral galaxy with observable star formation ongoing, though at such a low rate as to be a stable non-]starburst galaxy
A starburst galaxy is one undergoing an exceptionally high rate of star formation, as compared to the long-term average rate of star formation in the galaxy, or the star formation rate observed in most other galaxies.
For example, the star format ...
. It is a somewhat tenuous spiral galaxy with a very low surface brightness of just 23.8 mag/squ arc sec.
IC 5332 has also been observed in detail by the James Webb Space Telescope's Mid-InfraRed Instrument (MIRI). MIRI's high-resolution mid-infrared image pierced the dust clouds obscuring the galaxy's spiral arms, revealing the galaxy's structures in high detail. These structures were previously hidden in both visible and ultraviolet light observations.
IC 5332 Group
According to A.M. Garcia, IC 5332 is the namesake of the IC 5332 galaxy group
A galaxy group or group of galaxies (GrG) is an aggregation of galaxies comprising about 50 or fewer gravitationally bound members, each at least as luminous as the Milky Way (about 1010 times the luminosity of the Sun); collections of galaxi ...
(also known as LGG 478). This small group has three galaxies, including NGC 7713 and PGC 72525.
