NGC 3187


NGC 3187, also known as HGC 44D, is a large barred spiral galaxy located in the constellation Leo. Its velocity relative to the cosmic microwave background is 1,901 ± 22 km/s, which corresponds to a Hubble distance of 28.0 ± 2.0 Mpc. NGC 3187 was discovered by Irish physicist George Stoney in 1850.
The luminosity class of NGC 3187 is III and it has a broad HI line. It also contains regions of ionized hydrogen.
With a surface brightness equal to 15.30 mag/am^2, NGC 3187 is classified as a low surface brightness galaxy. LSB galaxies are diffuse galaxies with a surface brightness less than one magnitude lower than that of the ambient night sky.
To date, eight non-redshift measurements yield a distance of 25,700 ± 10,409 Mpc, which is within the Hubble distance range.
