NGC 210 is a barred spiral galaxy located roughly 67 million light-years from the Solar System in the constellation Cetus. It was discovered on October 3, 1785 by William Herschel and later added to the New General Catalogue.

Physical properties[edit]

It appears to be in loose association with NGC 157 and NGC 131. It is noted for its peculiar arms, which appear to be in the process of becoming a ring galaxy. They also have several apparently dense regions throughout them. The inner part of the galaxy appears to be lenticular, with a dust lane in it. The nucleus of the galaxy appears much brighter than the rest of it, suggesting an Active galactic nucleus.


In the image at the right, 2MASX J00403079-1353088 is the edge-on galaxy directly below the brightest star in the image. It is possibly a satellite of NGC 210, but without a redshift to determine its distance, it could just as possibly be completely unrelated to NGC 210.


15.9 magnitude SN 1954R was observed on September 7 in the outer edge of NGC 210's left arm and is likely associated with the galaxy.[6]
