NGC 5555 is a distant spiral galaxy located in the constellation Virgo. Its velocity in respect to the cosmic microwave background is 11,200 ± 20 km/s, corresponding to a Hubble Distance of 165 ± 12 Mpc (~538 million light-years).[1] It was discovered by Ormond Stone in 1886 who described it as "very faint, small, irregularly round with a bright middle nucleus."[2]
The galaxy morphology of NGC 5555 is Sb,[3][4][5] and it is known to contain regions of ionized hydrogen.[1]
To date, three non-redshift measurements give NGC 5555 a distance of 151,000 ± 6.245 megaparsecs (~493 million light-years), which is just within Hubble distance values.[6]
