NGC 1232 - a spiral galaxy in the constellation Erydanu NGC 1232 was discovered on 20 October 1784 by the English astronomer William Herschel . It is a tenth the size of a spiral galaxy of type SAB ( rs) c in the constellation Erydanu . The New General Catalogue object is described as a fairly bright , very large, round, shining gradually toward the center , giving separate. Based on the speed of the recession , which is 1605 km / s, estimated the distance of the galaxy from the Solar System , it amounts to about 75 million light years. This estimate correlates well with independent measurements of distances, based on measurements of displacement of NGC 1232 the red , these measurements locate the galaxy at a distance of 45 to 75 million light years. Taking into account the angular dimensions of NGC 1232 , which amount to 7.4 to 6.5 arcmin , the diameter of the galaxy is estimated to be about 160 thousand light years. NGC 1232 and its small companion , NGC 1232A designated as PGC 11834 or are marked as Arp 41 So probably looks like our galaxy seen from the outside . This image was acquired by the telescope No. 1 team ESOs VLT at Mount Paranal on 21 September 1998. Color photo was obtained by submitting images in color ultraviolet U ( 360 nm) , blue B ( 420 nm) and red R ( 600 nm).
