NGC 3100 = NGC 3103 is a lens-shaped galaxy with an active nucleus of the Hubble type SB0 in the constellation Air Pump (Antlia) south of the ecliptic . It is estimated to be 108 million light years from the Milky Way and about 110,000 light years in diameter. Presumably it forms a gravitationally bound galaxy pair together with NGC 3095 .
In the same area of the sky are the galaxies NGC 3108 , IC 2526 , IC 2533 , IC 2539 .
The object was discovered by John Herschel on February 16, 1836 .
