satellite galaxy

基本解释

If that's so, theory predicts that thousands of dark matter clumps should surround the Milky Way, each holding a small satellite galaxy.
如果真的如此，根據理論預測，銀河系的周圍應該環繞著成千上萬的暗物質團簇，每個都含有一個小的衛星星系。
Explanation: A satellite galaxy of our own Milky Way, the Large Magellanic Cloud (LMC) is an alluring sight in dark southern skies and the constellation Dorado.
解說：我們銀河系中的伴星系——大麥哲倫星雲（LMC）——是在黑暗的南天天穹中劍魚座的一道迷人的風景。
Less than 20,000 light-years across, the small island universe is similar in size, and often compared to our Milky Way's satellite galaxy, the Large Magellanic Cloud (LMC).
例如NGC 4449，距離我們約1200萬光年，寬度小於2萬光年，其大小與銀河系的衛星星系-大麥哲倫星系（LMC）相倣。
