Asteroids millions of them move between the orbits of Jupiter and Saturn.

Explanation

To solve the question regarding the statement about asteroids moving between the orbits of Jupiter and Saturn, we will analyze the information step by step.

### Step 1: Understand the Location of Asteroids
Asteroids are primarily found in a specific region of space known as the asteroid belt. This belt is located between the orbits of two planets.

**Hint:** Recall the specific planets that define the boundaries of the asteroid belt.

### Step 2: Identify the Correct Planets
The asteroid belt is located between the orbits of Mars and Jupiter, not between Jupiter and Saturn. This is a crucial detail that clarifies the original statement's inaccuracy.

**Hint:** Think about the order of the planets from the Sun and where the asteroid belt fits in.

### Step 3: Define Inner and Outer Planets
The classification of planets into inner and outer categories is based on their position relative to the asteroid belt. The inner planets are those that are located inside the asteroid belt, while the outer planets are those located outside of it.

**Hint:** List the planets in order from the Sun to help visualize which are considered inner and outer.

### Step 4: Conclude the Statement's Validity
Since the original statement claims that asteroids move between Jupiter and Saturn, and we have established that the asteroid belt is actually between Mars and Jupiter, we can conclude that the statement is false.

**Hint:** Consider how the position of the planets affects the classification of the statement.

### Final Conclusion
The statement "Asteroids millions of them move between the orbits of Jupiter and Saturn" is false. The correct information is that asteroids mainly reside in the asteroid belt, which is located between the orbits of Mars and Jupiter.

### Summary of Steps:
1. Understand the location of asteroids.
2. Identify the correct planets (Mars and Jupiter).
3. Define inner and outer planets.
4. Conclude the validity of the statement.
