NGC 4452 is a lenticular dwarf galaxy of the Hubble type S0 in the constellation Virgo on the ecliptic . It is estimated to be 6 million light years from the Milky Way and about 5,000 light years across . It is listed as a member of the Virgo galaxy cluster under catalog number VCC 1125 . The galaxy's radial speed of 165 km / s is too low compared to the peculiar speeds (non-Hubble expansion) to estimate the distance. Redshift independent distance estimates estimate the distance to be around 50 to 55 million light years.
The galaxies IC 794 , IC 3381 , IC 3413 , IC 3418 are located in the same area of the sky .
The object was discovered on March 15, 1784 by William Herschel with his 47 cm reflecting telescope .
