Textbook Question
Chapter 7, Problem 14EAP
Does it Make Sense?
Decide whether the statement makes sense (or is clearly true) or does not make sense (or is clearly false). Explain clearly; not all of these have definitive answers, so your explanation is more important than your chosen answer.
14. If Pluto were as large as the planet Mercury, we would classify it as a terrestrial planet.

Let's use Kepler's laws for the inner planets. Use the following distances from the sun to calculate the orbital period for each of these planets. Express your answer in terms of Earth years to two significant figures. Answer for the highlighted planet in each question.
Note: Use Kepler's law directly. Don't just Google the answers, as they will be a little bit different.
When you have calculated them, only submit the value for Earth.

Problem 4. Physical Features of the Giant Planets: Volume and Density of Jupiter (Palen, et. al. 1st Ed. Chapter 8 Problem 57 )
Jupiter is an oblate (Links to an external site.) planet with an average radius of 69,900 km, compared to Earth’s average radius of 6,370 km.
How many Earth volumes could fit inside Jupiter?
Jupiter is 318 times as massive as the Earth. How does Jupiter’s density compare (Links to an external site.) to that of Earth?
We need to create a scale model of the solar system (by shrinking the sun down to the size of a basketball or ~30cm). First, we will need to scale down actual solar system dimensions (planet diameters and average orbital radiuses) by converting our units. There are two blank spaces in the table below. We will effectively fill in the missing data in the next set of questions. Use the example below to help you.
Example: What is the scaled diameter of Mercury if the Sun is scaled to the size of a basketball (30 cm)?
The actual diameter of Mercury is 4879 km
The Sun's diameter is 1392000 km
If the Sun is to be reduced to the size of a basketball, then the conversion we need for this equation will be:
30cm1392000km
Here is how we run the conversion: 4879km×30cm1392000km=0.105cm or 0.11cm if we were to round our answer.
This means that if the sun in our model is the size of a basketball, Mercury is the size of a grain of sand. We can also see by looking at the table, that we would…
