NGC 5885 is an intermediate barred spiral galaxy located in the constellation Libra. Its speed relative to the cosmic microwave background is 2,185 ± 13 km/s, which corresponds to a Hubble distance of 32.3 ± 2.3 Mpc (~105 million ly).[1] NGC 5885 was discovered by German-British astronomer William Herschel in 1784.[2]
The luminosity class of NGC 5885 is III and it has a broad HI line. It also contains regions of ionized hydrogen. With a surface brightness equal to 14.39 mag/am2, we can qualify NGC 5885 as a low surface brightness galaxy (LSB). LSB galaxies are diffuse galaxies with a surface brightness less than one magnitude lower than that of the ambient night sky.[3]
To date, 11 non-redshift measurements yield a distance of 22.055 ± 5.687 Mpc[4] (~71.9 million ly),[5] which is outside the distance values of Hubble. Note that it is with the average value of independent measurements, when they exist, that the NASA/IPAC database calculates the diameter of a galaxy and that consequently the diameter of NGC 5885 could be approximately 37, 5 kpc (~122,000 ly) if we used the Hubble distance to calculate it.
