Object name: NGC4147
NGC 4147 is a globular cluster Coma Berenices about 63,000 light-years from us and 70,000 light-years from the center of the galaxy so it is in the far outer reaches of our galaxy's halo well above the galaxies plane. It was discovered by William Herschel on March 14, 1784. A few weeks earlier, on February 15, 1784 he found an object now listed as NGC 4153. There is nothing at that position. Some think it was really what we now know as NGC 4147. SIMBAD considers it non-existent. Others including NED and my database in The Sky say the two are the same object.
