NGC 4642 is a Spiral Galaxy in the Virgo constellation. NGC 4642 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. Given its B magnitude of 13.8, NGC 4642 is visible with the help of a telescope having an aperture of 14 inches (350mm) or more.

NGC 4642 is a Spiral Galaxy located in the constellation of Virgo in the equatorial region. NGC 4642's distance from Earth is 136,082,225.47 light years. NGC 4642 is called NGC 4642 in the New General Catalogue (NGC). This catalogue is a list of deep space objects compiled by John Louis Emil Dreyer in 1888 to update John Herschel's earlier work.

From Virginia Beach , NGC4642 is visible in the morning sky, becoming accessible around 22:42, when it reaches an altitude of 21° above your eastern horizon. It will then reach its highest point in the sky at 02:49, 52° above your southern horizon. It will be lost to dawn twilight around 05:43, 34° above your south-western horizon.

2019年8月27日 · NGC 4666 は、ESO 1036 (2010/09/01)によれば、距離8000万光年にあるスターバースト銀河で、伴星雲NGC 4668との激しい重力相互作用により爆発的な星形成が行われている銀河とされています。 超新星爆発と大質量星からの強烈な恒星風によって銀河から外部への大量なガスの流れ「スーパーウインド」が発生していて、主にX線でその状況が観測されたとされています。 ただ、NEDの資料ではスターバースト銀河には分類されていません、超新星 …

NGC 4632 is a spiral galaxy in the constellation of Virgo. Its velocity with respect to the cosmic microwave background for is 2,061 ± 24 km/s, which corresponds to a Hubble distance of 99.2 ± 7.0 Mly (30.40 ± 2.16 Mpc). [1] . However, 15 non-redshift measurements give a much closer distance of 54.12 ± 3.04 Mly (16.593 ± 0.931 Mpc). [2] .
