NGC 2151 是 剑鱼座 的一個 星系。

NGC 2151 is a Open Cluster in the Dorado constellation. NGC 2151 is situated south of the celestial equator and, as such, it is more easily visible from the southern hemisphere. The image below is a photograph of NGC 2151 from the Digitized Sky Survey 2 (DSS2 - see the credits section) taken in the red channel. The area of sky represented in ...

The Hercules Cluster (Abell 2151) is a cluster of about 200 galaxies [4] some 500 million light-years distant in the constellation Hercules. It is rich in spiral galaxies and shows many interacting galaxies. [5] The cluster is part of the larger Hercules Supercluster, which is itself part of the much larger Great Wall super-structure.

2024年6月2日 · Point your telescope with the widest field of view between the 5.1 mag star r Herculii and binary star κ Herculii (5.0 mag and 6.2 mag, 27" separation). The centre of the cluster lies west of the 6.7 mag star HD 144149 and roughly stretches in north-south direction.

NGC 2151 est un amas ouvert situé dans la constellation de la Dorade. Cet amas est situé dans le Grand Nuage de Magellan. Il a été découvert par l'astronome britannique John Herschel en 1835.

Abell 2151 is a mighty cluster of galaxies with a surplus of beautiful interacting galaxies. Interestingly its distribution is quite chaotic and lacks the typical central elliptical galaxy that is a common feature of most galaxy clusters. However the brightest galaxy is the elliptical NGC 6041.

NGC 2151是剑鱼座的一个星系，是约翰·弗里德里希·威廉·赫歇尔发现于1835年1月31日。

The constellation of Hercules is perhaps more associated with globular clusters than galaxies but it does contain the spectacular cluster Abell 2151. Unlike other galaxy clusters such as Coma (AGC 1656), the Hercules cluster is dominated by spiral galaxies.
