Question

Calculate: A year is the time it takes a planet to complete one orbit. Use your data to estimate the Year length for each planet. Use time units of Earth years or Earth months. Why does it take the outer planets so long to orbit the Sun? Try to come up with 2 reasons.

Answer 1

1. Mercury-$88$ Earth days/Months &$29$ days
2. Venus-$225$ Earth days/$7$ months &$13$days.
3. Earth-$365.25$ days/$12$ month/$1$ year.
4. Mars-$687$Earth days/$1$ year/$10$ months &$18$ days
5. Jupiter-$12$years.
6. Saturn-$30$ years.
7. Uranus-$84$ years.
8. Neptune-$164.8$ years
9. Pluto-$248$ years.

Explanation:

• Outer  planets take longer to orbit the sun because the gravitational pull is weaker as shown in the inverse square law.
• The outer planets are further away meaning they have more distance to cover in their orbit.
