NGC 4005 is a spiral galaxy in the Leo constellation, located close to the border with the Coma Berenices. [1] [2] [3] [4] A faintly-glowing galaxy, its apparent magnitude is 13.0.

The American astronomer Barbara A. Williams in 1986 noted that when observations are made of 23 galaxies centred on NGC 4005, a trend is found along the major axis of the group. The correlation in the group between position and velocity's slope is greatly different from 0. Williams put forward the explanation for this that the group rotates with a period of less than 4 billion years, however other interpretations have been discussed. [5]

It was discovered by William Herschel on 6 April 1785.

<i>New General Catalogue</i> Astronomical catalogue of deep sky objects

The New General Catalogue of Nebulae and Clusters of Stars is an astronomical catalogue of deep-sky objects compiled by John Louis Emil Dreyer in 1888. The NGC contains 7,840 objects, including galaxies, star clusters and emission nebulae. Dreyer published two supplements to the NGC in 1895 and 1908, known as the Index Catalogues, describing a further 5,386 astronomical objects. Thousands of these objects are best known by their NGC or IC numbers, which remain in widespread use.
