2021年1月21日 · NGC 4151 (UGC 7166, PGC 38739 and at least 50 other designations according to SIMBAD) is a Seyfert 1 (https://en.wikipedia...eyfert_galaxies) galaxy with a bright core and faint arms. While papers show varying distance estimates, the newest is approximately 60 million light-years away in Canes Venatici.

2020年3月31日 · The Eye of Sauron, also known as NGC 4151, UGC 7166 and PGC 38739, is an Intermediate Spiral Seyfert Galaxy, located inside Canes Venatici Constellation (Hunting Dog Constellation).

NGC 4151 is a Seyfert 1 Galaxy located in the constellation of Canes Venatici in the northern hemisphere. NGC 4151's distance from Earth is 32,338,404.85 light years. NGC 4151 is called NGC 4151 in the New General Catalogue (NGC).

NGC 4151 is an intermediate spiral Seyfert galaxy with weak inner ring structure located 15.8 megaparsecs (52 million light-years) from Earth [4] in the constellation Canes Venatici. The galaxy was first mentioned by William Herschel on March 17, 1787; it was one of the six Seyfert galaxies described in the paper [5] which defined the term.

A northern NGC4145 has an elliptical shape with a long axis of a bit smaller than 6 arc minutes. Another southern one has an ID of NGC4151, having an elliptical central bulge and extraordinary dimmed arms wound around it. The galaxy is one of the closest Seyfert galaxies in which the massive black holes are positioned.
