In what ways are Terrestrial planets different from Jovian planets? Why are planets and satellite round while asteroids irregular? Why do Uranus and Neptune appear to be blue? How does the earth's moon compare to moons of gas giant planets? Why is it important for scientist to determine the temperature ,age and composition of other stars and planets? What are the properties of terrestrial and gaseous planets.? What are gaseous planets composed of? Why are outer planets gaseous in nature whereas inner planets in our solar system are rocky? How are gaseous planets formed? How did gas giant planets form? How do gaseous planets form? Do planets ever fall out of orbit? Why do astrophysicists believe they could study the origins of the universe easier from the moon than they can on earth? How did Iron come to earth (millions of years ago)? How can meteorites cause catastrophic extinction? How do meteorites affect the earth? Why is it believed that warm dense matter exists at the core of some planets? Why does our planet have magnetic polarity with two poles? Why do refractory metals have high melting points? What component of Venus’ atmosphere causes the planet to be so hot? Which planets have the greenhouse effect? How does the greenhouse effect work? On which planet is it the strongest? What is the size of the smallest feature that could be distinguished on the surface of Venus (at closest approach) by the Arecibo radio telescope at an angular resolution of 1″? Suppose you want to determine the chemical composition of a distant planet or star. What equipment will be most useful to have? What is the difference between brown dwarfs and Jupiter? How are Brown Dwarfs like jovian planets? How do scientist measure the mass of the planets? What is the size of Saturn? In what ways is Jupiter similar/different to Earth? What methods are used to detect planets around distant stars? How many planets are there in total? Why is the direct detection of exoplanets difficult? How many satellites have been discovered so far in the solar system? What is the exact distance from Earth to Neptune? What are the parameters for new definitions of a Planet? What planets have plate tectonics? Which planets in our solar system have plate tectonics which closely mirror that of Earth's? Why don’t other planets and moons in our solar system show signs of plate tectonics? Is the Earth the only planet in the solar system known to have plate tectonics? Do any moons have plate tectonics? What are the four processes that shape the surface of planets and satellites? What is the size of the planet Saturn? What is the scientific reasoning for the order of the planets? Why do other planets exist? Why are the Jovian planets so much larger than the terrestrial planets? Which planet do you think could be colonized, and what technological advancements would it require? Does all the Carbon on earth come from dead stars? What are the two main differences between extrasolar planetary systems discovered to date and our Solar System? Are stars with planetary systems very common or extremely rare? The composition of a planet's atmosphere can be measured during a transit by analyzing what? A spectral line from the left side of Saturn's rings, as you see them, is at a wavelength slightly shorter than the same spectral line measured from the right side of Saturn’s rings.
