矮星系 NGC 147 (倒爿) kah NGC 185 tī 這幅望遠鏡畫面內底徛相倚。 這兩个毋是 離咱 250 萬光年遠 ê 大捲螺仔 - 仙女座星系 M31 定定講著 ê 衛星星系。 In tī 天頂這幅美麗 ê 視野內底 ê 角距離比 1 度較細。 按照仙女座星系 ê 距離 來推算，in 兩个 ê 距離差不多有 3 萬 5 千 光年遠。 是講仙女座星系無 tī 這幅圖內底。 仙女座星系較光、較有名 ê 衛星星系是 M32 kah M110。 In 離 大捲螺仔 較近。 NGC 147 kah NGC 185 去予人辨識做雙星系。 In 是 重力穩定 ê 一組雙星系系統。 毋閣最近發現著一个較暗 ê 矮星系 - 仙后座 II，敢若嘛是這个系統 ê 一部份。 In tī 仙女座內底，因為重力相縛，煞形成一陣迷人 ê 小小 衛星星系群。

[English] NGC 147 and NGC 185

Dwarf galaxies NGC 147 (left) and NGC 185 stand side by side in this sharp telescopic portrait. The two are not-often-imaged satellites of M31, the great spiral Andromeda Galaxy, some 2.5 million light-years away. Their separation on the sky, less than one degree across a pretty field of view, translates to only about 35 thousand light-years at Andromeda's distance, but Andromeda itself is found well outside this frame. Brighter and more famous satellite galaxies of Andromeda, M32 and M110, are seen closer to the great spiral. 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.
