What does exo mean? From a little girl? Please translate it into Chinese.

EXO is a 12 men's team officially launched by SM Entertainment Company of Korea on April 8, 20 12.

The name EXO comes from the word EXOPLANET, which means exoplanets outside the solar system, implying that they are new stars from the unknown world. After EXO, K representing Korean and M representing Mandarin were added to form two groups, namely EXO-K and EXO-M, which launched activities in South Korea and China respectively.
