History

The galaxy NGC 488 was discovered on 13 December 1784 by the German-British astronomer William Herschel with his self-made 18.7 inch f/12.8 reflector telescope in Slough, England. On 6 December 1850, the engineer Bindon Stoney roamed the 72 inch reflector telescope in Birr Castle, Ireland «Leviathan» of his employer William Parsons, the 3rd Earl of Rosse this region of the starry sky and came across the small galaxies NGC 486, NGC 490, NGC 492 and NGC 500. [196, 277]

Physical Properties

The galaxy NGC 488 shows a redshift of z ≈ 0.0075, which corresponds to a distance of about 29.3 Mpc to 30.5 Mpc. NGC 490 shows a similar redshift of z ≈ 0.0074. NGC 486, NGC 492 and NGC 500 show a much higher redshift of z ≈ 0.04, which suggests a much greater distance. [145]
