Galaxy in the Virgo constellation
NGC 4458 is an
elliptical galaxy located about 54 million
light-years away
[3]
[4] in the
constellation of
Virgo .
[5] It was discovered by astronomer
William Herschel on April 12, 1784.
[6] NGC 4458 is a member of
Markarian's Chain which is part of the
Virgo Cluster .
[7] It is in a pair with the galaxy
NGC 4461 .
[8] NGC 4458 and
NGC 4461 are interacting with each other.
[9]
NGC 4458 may have a
supermassive black hole with an estimated mass of 200 million Suns ( 2× 108
M☉ ).
[2]
Nuclear disk
NGC 4458 has an edge-on nuclear disk which is estimated to be about 6 billion years old.
[10] The disk likely formed from the merger of a gas-rich galaxy and has been found to have "similar properties to the decoupled cores of bright ellipticals".
[11]
[12]
Counter-rotating core
Using Hubble images, it has been determined that NGC 4458 has a counter-rotating core.
[9]
Metallicity
NGC 4458 has a low metal content but has an overabundance of the element
iron .
