dwarf elliptical galaxy : ウィキペディア英語版 | dwarf elliptical galaxy Dwarf elliptical galaxies, or dEs, are elliptical galaxies that are much smaller than others. They are classified as dE, and are quite common in galaxy groups and clusters, and are usually companions to other galaxies. == Examples == One of the most nearby Dwarf ellipticals (''dE''s) is M32, a satellite of the Andromeda Galaxy. In 1944 Walter Baade confirmed dwarf ellipticals NGC 147 and NGC 185 as members of the Local Group by resolving them into individual stars. Resolving stars in NGC 147 and NGC 185 was only possible because these dEs are very nearby galaxies. In the 1950s, dEs were also discovered in the nearby Fornax and Virgo clusters.〔G. Reaves (1956), (Dwarf galaxies in the Virgo cluster )〕
