NGC 3854 = NGC 3865 is a merging bar-spiral galaxy of the Hubble type SBb in the constellation Becher in the southern sky . It is estimated to be 249 million light years away from the Milky Way and has a diameter of about 110,000 ly. In the same area of the sky there is u. a. the galaxy NGC 3858 .
The object was discovered in 1880 by the astronomer Andrew Common with his 36-inch reflector telescope. In 1886 the astronomer Francis Preserved Leavenworth observed an object at a similar point, which is listed in the New General Catalog under NGC 3854 ; it is now assumed that NGC 3865 will be observed again .
