M110或梅西耶110也称为NGC 205，是仙女座星系的卫星星系，而在分类上是一个矮椭圆星系^[7]。尽管查尔斯·梅西耶从未将该星系列入他的星云表中，但在他的一张仙女座星系的图纸上描绘了M32和这个星系；图纸上的标签注明梅西耶于1773年8月10日首次观测到NGC 205 ^[8]。卡罗琳·赫歇尔在1783年8月27日也独立发现这个星系；他的哥哥威廉·赫歇尔在1785年描述了她的发现^[9]^[8]。在1967年，肯尼斯·格林·琼斯（Kenneth Glyn-Jones）提出将此星系列入梅西耶天体表的建议^[10]，使之成为梅西耶天体的最后一个成员。

这个星系的型态分类为de5pec，表示为扁率50%的奇特矮椭圆星系。M110被归类为奇特，是因为在中心附近有尘埃和年轻的蓝色恒星^[11]。对矮椭圆星系而言，这是不平常的^[7]，造成这种特殊的原因还不清楚^[11]。它还有些特征相当特殊，与一般的矮椭圆形星系不同。比如它似乎含有暗星云。此外M110虽然很小，但它周围有八个球状星团围绕它运行。不同于M32，没有证据显示在NGC 205的中心有超大质量黑洞^[12]。

M110中的星际尘埃质量为7034218740500000000♠(1.1–1.8)×10⁴ M_☉，温度为 7001180000000000000♠18–22 K，星际气体的质量为7036795420000000000♠(4–7)×10⁶ M_☉。M110的显示内部没有足够的星际物质，而这些物质可能是由超新星爆炸喷发出来的。可能是与M31交互作用的潮汐已经剥离了大量的气体和尘埃，使得整个星系的星际物质密度不足^[13]。

新星

在这个星系中也发现过一些新星，包括1999年发现的一颗^[14]，还有在2002年也检测到一颗。后者命名为EQ EQ J004015.8+414420，是在史隆数位巡天2002年10月拍摄的影像中检出的^[15]。

大约一半的仙女座星系的卫星星系正沿着一个高度平坦的平面围绕着主星系运行：16个中有14个遵循相同的旋转方向。有一个理论认为这些天体曾经属于NGC 205周围的一个亚哈洛星系，然后在与仙女座星系的一次近距离接触中，这群天体被潮汐力打破^[16]。

It shews the same faint colour with the great one, and is, no doubt, in the neighborhood of it. It is not [M32] … ; but this is about two-thirds of a degree north preceding it, in a line parallel to β and ν Andromedae."
