2024年9月16日 · Messier 110 is a satellite galaxy of the Andromeda Galaxy (M31). This Hubble observation of M110 was taken in visible and near-infrared light with the Wide Field and Planetary Camera 2. The galaxy's core is seen toward the lower right of the image, with its globular clusters and numerous stars shown as points of light throughout the frame.

据估计，M31的质量不小于3.110个太阳质量，比银河系大一倍以上，是 本星系群 中质量最大的一个。 M31的中心有一个类星核心，直径只有25光年，质量相当于10 太阳质量，即一 立方秒差距 内聚集1500个恒星。 类星核心的 红外辐射 很强，约等于银河系整个核心区的辐射。 但那里的射电却只有银心射电的1/20。 射电观测指出，中性氢多集中在半径为10千秒差距的宽环带中。 氢的含量为总质量的1%，这个比值较之银河系的（1.4～7%）要小。 由此可以认为，M31的气体大部 …

M110 (NGC 205)椭圆星系，在仙女座，在M31的西北面，是M31第二亮的伴星系，因此也是本星系群的一员，M110一般被定型为E6p，但它有些特征相当特殊，与一般的椭圆形星系不同。 比如它似乎含有暗星云，因此有人也称它为椭圆体状矮星系。 此外M110虽然很小，但它周围有八个球状星团围绕它运行。

Messier 32 is above the galactic nucleus and Messier 110 is at the bottom. The Andromeda Galaxy is a barred spiral galaxy and is the nearest major galaxy to the Milky Way. It was originally named the Andromeda Nebula and is cataloged as Messier 31, M31, and NGC 224.

The Astronomical League rates M31 “Easy” with 7X50 binoculars, although they rate M32 a “Challenge” and M110 as not visible. To find M31 with binoculars, the first step is to find Mirach, which is beta-Andromedae, the second brightest star in the constellation Andromeda.

m110或梅西耶110也稱為ngc 205，是仙女座星系的衛星星系， 而在分類上是一個矮橢圓星系 [7] 。 儘管 查爾斯·梅西耶 從未將該星系列入他的 星雲表 中，但在他的一張仙女座星系的圖紙上描繪了 M32 和這個星系；圖紙上的標籤註明梅西耶於1773年8月10日首次觀測到NGC ...

2023年11月21日 · The brightest of these is 9th-magnitude M32, located half a degree south of M31. The other satellite is M110, one degree northwest of M31. These two satellite galaxies are pretty faint, and the key to viewing them is to set up your scope away from local lights on a dark, transparent, moonless night.

Messier 110 or M110 (also designated NGC 205) is a dwarf elliptical galaxy in the constellation Andromeda. It has an apparent visual magnitude of 8.5 and its angular diameter is 17x10 arc-minutes. M110 lies at an estimated distance of 2.9 million light years.

m31、m32、m110 (ｱﾝﾄﾞﾛﾒﾀﾞ星雲) ★見える場所 と特徴 M31、M32は、アンドロメダ大星雲（銀河）と呼ばれる大型の渦巻き銀河でアンドロメダ座にある皆さんよくご存じの銀河です。

The Great Andromeda Galaxy is the nearest major spiral galaxy to our own Milky Way. It’s catalogued as M31 (along with its satellites M32 and M110), located 2.5 million light years away, stretching some 200.000 light years across. [1] Our Galaxy is thought to look much like Andromeda, a great spiral.
