PGC 29963 is a compact galaxy of Hubble type C in the constellation Leo. It is estimated to be 371 million light years from the Milky Way .
The position of NGC 3186 was recorded on March 25, 1865 by astronomer Albert Marth, but there is nothing there that fits his description. Professor Seligman therefore claims that the entry concerns an object that affects a lost or non-existent celestial body. Near these coordinates, in the constellation Leo, there are two candidates for NGC 3186. The NASA / IPAC database and Wolfgang Steinicke identify the galaxy PGC 29963 as NGC 3186, while the Simbad and HyperLeda databases choose PGC 30058. There is no way to choose between these two candidates. However, the NASA / IPAC database shows that this identification is unsafe.
