Scientists have discovered 12 new moons around Jupiter， putting the totalcount at a record-breaking 92. Thats more than any other planet in our solarsystem2. Saturn3 comes in a close second with 83 moons. These newest moons rangein size from one kilometre to three kilometres. The small moons of Jupiter and Saturnare believed to be the results of once bigger moons that collided4 with one another.Jupiters newly discovered moons have yet to be named. Only half of them are bigenough—at least 1.5 kilometres or so in size—to qualify5 for a name.

科學家们在木星周围发现了12 颗新的卫星，木星的卫星总数达到了创纪录的92 颗。这比太阳系中的任何其他行星都多。土星以83 颗卫星的数量紧随其后。这些新发现的卫星直径从一千米到三千米不等。木星和土星的小卫星被认为是曾经较大的卫星彼此碰撞的结果。新发现的木星卫星尚未被命名。其中只有一半的卫星足够大———直径至少在1.5 千米左右———有资格获得一个名字。
