NGC 5100 = NGC 5106 is a spiral galaxy of the Hubble type S with an active galaxy core in the constellation Virgo on the ecliptic . It is an estimated 426 million light years away from the Milky Way and about 100,000 light years in diameter. Together with PGC 46603 (also NGC 5100-2 ) it forms a gravitationally bound galaxy pair .
In the same area of the sky is u. a. the galaxy NGC 5080 .
The object was discovered twice; first discovered on January 23, 1784 by Wilhelm Herschel , who described it as “faint, very small” and noted in the register: “Sweep 108, Jan. 23, 1784. A very small and faint neb. sp 59 Virginis ... While I looked into the finder to determine its situation I lost it, but shall endeavor to find it another night ". This observation is listed as NGC 5106 . The second discovery followed on March 22, 1865 by Albert Marth and is listed as NGC 5100 .
