How might the presence of a planet the size of Jupiter affect the evolution of the Solar System?
If you could visit another planetary system while the planets are forming, would you expect to see the condensation sequence at work, or do you think that process was most likely unique to our Solar System? How do the properties of the extrasolar planets discovered so far affect your answer?
Do you expect the most planetary system in the Universe have analogs to our Solar System’s asteroid belt and Kuiper Belt? Would all planetary systems show signs of an age of heavy bombardment?
If the solar nebula hypothesis is correct, do you think there are more planets in the Universe than stars? Why or why not?
15)Based on the information found in modules 2.1 , 2.2 AND 2.3 put the following statements about the formation of the Solar system based on the NEBULAR HYPOTHESIS in the correct order from 1. ‘’OLDEST EVENT’’ (first to form according to the Nebular hypothesis) to 5. ‘’YOUNGEST EVENT’’ (Last to form in the Solar system, based on the sequence of events listed) .
• Clusters of molten metals and dust particles stuck together to form rocks
• Lighter gases were swept away from center of solar system into outer solar system
• One to two proto-planets collide to form our Moon
• Mutual gravity caused rocks to come together, eventually to form protoplanets
• Heavier rocky material, with metallics with higher melting points are left nearer to sun

- Look at Figure 21-11. Which molecule(s) can escape from Earths gravity? From Mars? From Venus? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies. The lines represent the typical highest velocities of molecules of various masses. The Jovian planets have high escape velocities and can hold onto even the lowest-mass molecules. Mars can hold only the more massive molecules, and the Moon has such a low escape velocity that even massive molecules can escape.arrow_forwardHow does the solar nebula theory explain the significant density difference between the Terrestrial and Jovian planets?arrow_forwardReview Figure 21-11.
