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，根据理论预测，银河系的周围应该环绕着成千上万的暗物质团簇，每个都含有一个小的卫星星系。
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.
解说：我们银河系中的伴星系——大麦哲伦星云（LMC）——是在黑暗的南天天穹中剑鱼座的一道迷人的风景。
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，距离我们约1200万光年，宽度小于2万光年，其大小与银河系的卫星星系-大麦哲伦星系（LMC）相仿。
