Answer 1

To order the planets from smallest to largest diameter, we compare their diameters:

• Mercury: \(4.87 \times 10^3\) kilometers
• Mars: \(6.79 \times 10^3\) kilometers
• Earth: \(1.28 \times 10^4\) kilometers
• Venus: \(1.21 \times 10^4\) kilometers

Converting all values for easier comparison:

• Mercury: \(4.87 \times 10^3 = 4870\) kilometers
• Mars: \(6.79 \times 10^3 = 6790\) kilometers
• Earth: \(1.28 \times 10^4 = 12800\) kilometers
• Venus: \(1.21 \times 10^4 = 12100\) kilometers

Now, we can list them in order from smallest to largest:

1. Mercury: 4870 kilometers
2. Mars: 6790 kilometers
3. Venus: 12100 kilometers
4. Earth: 12800 kilometers

So the ordered list from smallest to largest diameter is:

Mercury, Mars, Venus, Earth.
