Use the planetary data in Table 7.1 and Appendix E to answer each of the following. a. Which column of data would you use to find out which planet has the shortest days? Do you see any notable differ- ences in the length of a day for the different types of plan- ets? Explain.   b. Which planets should not have seasons? Why? c. Which column tells you how much a planet’s orbit deviates from a perfect circle? Based on that column, are there any planets for which you would expect the surface temperature to vary significantly over its orbit? Explain.
