Spiral Galaxy NGC 3953:
NGC 3953 is a spiral galaxy in the constellation of Ursa Major. It has a small, very bright active nucleus in a bright inner lens: 0.5 x 0.3 arc min. There is an inner ring structure just beyond the nucleus that is about 1.2 x 0.55 arc min. There are many knotty filamentary spiral arms and it has an anonymous companion galaxy near by.
Based on the published red shift, (and a Hubble Constant of 62 Km/sec per Mpc) a rough distance estimate for NGC 3953 is 56 million light years, with a diameter of about 111,400 light years.
