The Small Magellanic Cloud (SMC) is a dwarf galaxy near the Milky Way. [5] Classified as a dwarf irregular galaxy , the SMC has a D 25 isophotal diameter of about 5.78 kiloparsecs (18,900 light-years), [ 1 ] [ 3 ] and contains several hundred million stars. [ 5 ]
The Large Magellanic Cloud and its neighbour and relative, the Small Magellanic Cloud, are conspicuous objects in the southern hemisphere, looking like separated pieces of the Milky Way to the naked eye. Roughly 21° apart in the night sky, the true distance between them is roughly 75,000 light-years.
The compiler of the New General Catalogue, Danish astronomer John Louis Emil Dreyer, described this object as "pretty bright, pretty small, little extended, very gradually brighter middle". [6] The cluster is located at a distance of around 200,000 light-years (60 kpc ) from the Sun. [ 1 ]
The Large Magellanic Cloud is a satellite galaxy of the Milky Way, as is another nearby galaxy called the Small Magellanic Cloud. Both are smaller than our galaxy and offer different galactic ...
NGC 290 is an open cluster of stars in the southern constellation of Tucana.This cluster was discovered September 5, 1826, by Scottish astronomer James Dunlop. [7] It lies some 200,000 light years away from the Sun in the Small Magellanic Cloud galaxy.
This is a list of known galaxies within 3.8 megaparsecs (12.4 million light-years) of the Solar System, in ascending order of heliocentric distance, or the distance to the Sun. This encompasses about 50 major Local Group galaxies, and some that are members of neighboring galaxy groups , the M81 Group and the Centaurus A/M83 Group , and some ...
Utilizing the Cepheid Period-Luminosity relationship, Hubble determined a distance of 214 kiloparsecs or 698,000 light-years. This was the first system beyond the Magellanic Clouds to have its distance determined. (Hubble continued this process with the Andromeda Galaxy and the Triangulum Galaxy).
This makes it feasible to use them as indicators of distance. Recently, they have been used to give direct distance estimates to the Large Magellanic Cloud (LMC), Small Magellanic Cloud (SMC), Andromeda Galaxy and Triangulum Galaxy. Eclipsing binaries offer a direct method to gauge the distance to galaxies to a new improved 5% level of accuracy ...
