NGC 4607 is an edge-on spiral galaxy located about 56 million light-years away[2] in the constellation Virgo.[3] NGC 4607 was discovered by astronomer R. J. Mitchell on April 24, 1854.[4] The galaxy is a member of the Virgo Cluster.[5][6]

Interaction with NGC 4606

[edit]

NGC 4607 may be a possible companion of NGC 4606[7] and they are separated from each other by a projected distance of about ~55,000–65,000 ly (17–20 kpc).[8][9] Despite this, NGC 4607 does not show any evidence in the optical or H I of having been tidally disturbed[9] unlike NGC 4606.[9][8] This would be inconsistent if a strong tidal interaction has occurred between the two galaxies.[8] Also, both galaxies' redshifts differ by about 600 km/s making it unlikely that they are a gravitationally bound pair.[9]
