NGC 3421 Galaxy (IC 652) Updated : 04/02/2025. Introduction. NGC 3421 is a Spiral Galaxy located in the constellation of Hydra in the equatorial region. NGC 3421's distance from Earth is 282,712,348.19 light years. NGC 3421 is called NGC 3421 in the New General Catalogue (NGC).

NGC 3421 is a Barred Spiral Galaxy in the Crater constellation. NGC 3421 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 3421是位于长蛇座的一个星系。 它的赤经为 1050.8，赤纬为 -12° 27′。

2021年5月22日 · Historical Identification: Per Dreyer, NGC 3421 (Common (#8), 1860 RA 10 43 57, NPD 101 29) is one of "2 nebulae, faint, round", the other being NGC 3422. The second IC says of NGC 3421-22 "Only one seen by Howe, RA 10 44 00, NPD 101 42.4, two suspected north and southwest of it."

From Virginia Beach , NGC3421 is visible in the evening sky, becoming accessible around 20:22 (EDT), 22° above your south-eastern horizon, as dusk fades to darkness. It will then reach its highest point in the sky at 23:35, 40° above your southern horizon.

NGC 3421 (također poznat kao IC 652, MCG -2-28-13 i PGC 32514) je spiralna galaksija koja je udaljena oko 204 miliona sg od Zemlje i nalazi se u sazviježđu Vodena zmija. Najveći prečnik je 1,80 (107 hiljada sg) a najmanji 1,5 uglovnih minuta (89 hiljada sg).

NGC 3421 Galaxy in Hydra Dreyer's description: F, R . Cross Identifications: Common.

===== NGC 3421 = IC 652 and NGC 3422. Among the nebulae found in 1880 by A. A. Common are two that received these NGC numbers. Common gave them a single rough position -- there are only faint stars near it. However, ten arcmin south is a pair that he could have easily seen in his 36-inch reflector.
