NGC 4407 = NGC 4413 is a bar-spiral galaxy with extensive star formation areas of the Hubble type SBab in the constellation Virgo on the ecliptic . It is estimated to be 2 million light years from the Milky Way and is listed under catalog number VVC 912 as part of the Virgo Galaxy Cluster. The radial speed of NGC 4407 of 105 km / s is too low to provide a reliable indicator of the distance, as particular speeds (without Hubble expansion) could make up a significant part of the value. In fact, the distance of 2 million light years corresponding to its speed is far less than the redshift independent distance estimate of about 51 million light years.
In the same area of the sky are u. a. the galaxies NGC 4388 , NGC 4425 , IC 3349 , IC 3363 .
The object was discovered by Wilhelm Herschel on April 17, 1784 and accidentally recorded twice, so that two entries in the New General Catalog refer to this galaxy.
