14. Based on what the nebular theory tells us about the formation of our own solar system, what does the theory predict for the possibility of other planetary systems?

Procedure  Table 11.1 presents Djup and Pday for the major Jovian satellites. First use these data and the equation above to calculate Jupiter’s mass in kilograms (kg). Enter your results in the table for each satellite. Next calculate the average Jupiter mass (Mjup, av) and enter the result in the table. Finally, calculate the percent difference (PD) using Mjup, av and the standard value for Jupiter’s mass (1.9 X 1027 kg). In the calculation of PD you can ignore 1027 because it will appear in both numerator and denominator. ________________________________________________________ Table 11.1 Calculated values for Jupiter’s Mass Satellite               Djup       Pday         Mjup Io                       2.95       1.77 Europa              4.69        3.55 Ganymede        7.50        7.15 Callisto           13.15       16.7 __________________________________________________________ Average Jupiter Mass =                              Percent Difference =

Tutorial An asteroid has a 5:1 orbital resonance with Jupiter. What is its orbital period (in years)? How far is it from the Sun in AU? How does the distance between the orbits of Mars and the asteroid compare to the distance between the orbits of Mars and Jupiter? Part 1 of 3 Orbital resonances compare how many orbits a body, in this case an asteroid, makes in terms of the orbit of a much larger body, in this case Jupiter. We can write resonances as (number of orbits of smaller body): (number of orbits of larger body). Na:N, If we want to know the orbital period of the smaller body, we can express this as a relation. The second number tells us how many times the larger body orbits and the first number tells us how many times the smaller body orbits. If we want the orbital period, we just take the ratio of these and multiply by the orbital period of the larger body. N, Pa Na An asteroid has a 5:1 orbital resonance with Jupiter. What is its orbital period? P. = years

Question 7 What type of mission collects information about multiple planets? Sample returns. Rovers. Flybys. Atmospheric probes. Question 8 Why are neutrinos so difficult to detect? There are very few of them, so collecting enough to study takes a long time. They are theoretical and may not exist. They move so fast they pass right through the telescope. They don't interact strongly with matter, so they will not cause a reaction on a CCD imager.
