NGC 185 (also known as Caldwell 18) is a dwarf spheroidal galaxy located 2.08 million light-years from Earth, appearing in the constellation Cassiopeia. It is a member of the Local Group, and is a satellite of the Andromeda Galaxy (M31). [6] NGC 185 was discovered by William Herschel on November 30, 1787, and he cataloged it "H II.707". [6]

2024年8月23日 · Located in Cassiopeia, not far from Caldwell 17, Caldwell 18 is a dwarf galaxy and a satellite of the Andromeda galaxy. Also known as NGC 185, it is a member of the Local Group of galaxies.

2024年1月1日 · NGC 185 and NGC 147 are only one degree apart in the sky, and just over 7° north of the Andromeda Galaxy. Both are dwarf ellipticals found in M31’s outer halo, but farther out than M32 and NGC...

NGC 185 is a Elliptical Galaxy in the Cassiopeia constellation. NGC 185 is situated north of the celestial equator and, as such, it is more easily visible from the northern hemisphere. Given its visual magnitude of 9.2, NGC 185 is visible with the help of a binocular with a 60-70mm aperture or a small telescope.

2025年1月12日 · NGC 185 (PGC 2329, UGC 396, Caldwell 18 and others) is a dwarf spheroidal galaxy located approximately 2.15 million light-years away in Cassiopeia. It is a member of the Local Group and a satellite of M31.

3 天之前 · NGC 185's unique characteristics make it invaluable for astronomical research: It challenges existing models of dwarf galaxy evolution, forcing us to reconsider how these small galaxies form and change over time.

2023年8月7日 · The ground-based image of Caldwell 18 (NGC 185) in the top left is from the Digitized Sky Survey (DSS) and shows the sites of some additional Hubble observations of the galaxy.

NGC 185 is a Seyfert 2 Galaxy located in the constellation of Cassiopeia in the northern hemisphere. NGC 185's distance from Earth is 2,354,849.05 light years. NGC 185 is called NGC 185 in the New General Catalogue (NGC).

NGC 147 and NGC 185 have been identified as binary galaxies, forming a gravitationally stable binary system. But recently discovered faint dwarf galaxy Cassiopeia II also seems to be part of their system, forming a gravitationally bound group within Andromeda's intriguing population of small satellite galaxies .

NGC 185 was recognized as a Local Group member galaxy, together with its neighbor NGC 147, by Walter Baade (1944), when he resolved them into stars with the 100-inch reflector on Mt. Wilson. These two dwarf elliptical galaxies apparently form a physical pair, as they are only 58 arc minutes separated; according to Van den Bergh , they are ...
