The many moons of Jupiter travel around the planet in different directions（方向）．Jupiter is the largest planet in our solar system．Over the years，scientists have found that Jupiter has its own small solar system．Earth has one moon．Jupiter has at least sixteen and probably more．
Since there are so many moons，scientists began to number them．The numerals（numbers）tell the sequence，or order，in which the moons were found．They were slower to name the moons．All of Jupiter's moons now have a name as well as a number．
The first five moons to be discovered are known as the“inner moons”．But they are not the closest to the planet．The closest is only 127，600 kilometers away from Jupiter．All the inner moons circle the planet in counter-clockwise direction，that is，opposite of the hands of a clock．
Jupiter's middle group of moons are at least 11，100，000 kilometers from the planet．
They also move in a counter-clockwise motion（moving）．The four farthest moons are at least 20，700，000kilometers away．These are called“outer moons”．They circle in a clockwise motion． How many more moons do you thik will be discovered？
