NGC 4540 is a spiral galaxy with type 1 Seyfert activity [3] located about 64 million light-years away [4] in the constellation Coma Berenices. [5] NGC 4540 was discovered by astronomer William Herschel on March 21, 1784 [6] and is a member of the Virgo Cluster. [7][8]

NGC 4540 is a Intermediate Spiral Galaxy in the Coma Berenices constellation. NGC 4540 is situated close to the celestial equator and, as such, it is at least partly visible from both hemispheres in certain times of the year.

NGC 4540是位于后发座的一个星系。 它的赤经为12h34.8m，赤纬为15°33′，大小2′。

2022年7月2日 · NGC 4540 is a Spiral Galaxy located in the constellation of Coma Berenices in the northern hemisphere. NGC 4540's distance from Earth is 64,066,897.27 light years.

From Redmond , NGC4540 is visible in the morning sky, becoming accessible around 23:14, when it reaches an altitude of 21° above your eastern horizon. It will then reach its highest point in the sky at 04:11, 57° above your southern horizon. It will be lost to dawn twilight around 06:20, 48° above your south-western horizon.

On 21 March 1784 William Herschel, using a 18.7-inch f/13 speculum telescope, catalogued II-94 as"Faint, small." On 8 April 1784 he catalogued II-119 as "pretty large, resolvable." These observations refer to the same object.

A Hubble Space Telescope Census of Nuclear Star Clusters in Late-Type Spiral Galaxies. II. Cluster Sizes and Structural Parameter CorrelationsWe investigate the structural properties of nuclear star clusters inlate-type spiral galaxies. More specifically, we fit analytical modelsto Hubble Space Telescope images of 39 nuclear clusters in order todetermine their effective radii after correction ...
