| dbo:abstract | The Eridanus II Dwarf is a low-surface brightness dwarf galaxy in the constellation Eridanus. Eridanus II was independently discovered by two groups in 2015, using data from the Dark Energy Survey . This galaxy is probably a distant satellite of the Milky Way. . Eridanus II contains a centrally located globular cluster; and is the smallest, least luminous galaxy known to contain a globular cluster. . Eridanus II is significant, in a general sense, because the widely accepted Lambda CDM cosmology predicts the existence of many more dwarf galaxies than have yet been observed. The search for just such bodies was one of the motivations for the ongoing Dark Energy Survey observations. Eridanus II has special significance because of its apparently stable globular cluster. The stability of this cluster, near the center of such a small, diffuse, galaxy places constraints on the nature of dark matter. .

Encontra-se na constelação de Eridanus, localizada a 366 kpc da Terra. É classificada como uma galáxia anã esferoidal (dSph) o que significa que ela tem uma forma aproximadamente arredondada com um raio de cerca de 0,55 kpc. (pt) Eridanus II (DES J0344.3−4331) – galaktyka karłowata będąca galaktyką satelitarną Drogi Mlecznej. Galaktyka należy do grupy dziewięciu obiektów, których odkrycie ogłoszono w 2015, z których trzy są na pewno satelitami Drogi Mlecznej, a sześć pozostałych jest prawdopodobnymi, ale niepotwierdzonymi galaktykami karłowatymi. Galaktyka jest odległa o ponad 330 tysięcy parseków (ponad milion lat świetlnych). Masę gwiazd, które zawiera szacuje się na zaledwie 83 +17−14 tysięcy M☉. Obiekt przypomina wcześniej odkrytą galaktykę satelitarną Canes Venatici I, ale jest od niej bardziej odległa. (pl) |
