2017年3月30日 · Based on a recessional velocity of 895 km/sec, NGC 2146 is about 40 million light years away, in fair agreement with redshift-independent distance estimates of 55 to 90 million light years (peculiar (non-Hubble-expansion) velocities could have a significant effect on the recessional distance, so the difference is not unexpected).

Ages and Metallicities of Extragalactic Globular Clusters from Spectral and Photometric Fits of Stellar Population Synthesis Models Spectra of galaxies contain an enormous amount of information about therelative mixture of ages and metallicities of constituent stars.

NGC 2147 Cluster associated with nebulosity in Dorado Dreyer's description: eF, S, R, bM . Cross Identifications: GC 1341, h 2997. in LMC.

NGC 2147 é um aglomerado aberto com nebulosa na direção da constelação de Dorado. O objeto foi descoberto pelo astrônomo James Dunlop em 1826, usando um telescópio refletor com abertura de 9 polegadas. Devido a sua moderada magnitude aparente (+12,9), é visível apenas com telescópios amadores ou com equipamentos superiores.
