- What does the term differentiated mean when applied to a planet? Would you expect to find that planets are usually differentiated? Why?You are packing for a vacation on a planet orbiting another star that is much like the Sun. Why might you want some information about the planets orbit size and axis tilt to know what to pack?How Do We know? How can scientists know anything about how the Solar System formed, given that there was nobody there to witness those events?
- Which of the following observations would support the solar nebula theory over the passing star hypothesis? a. Proving that most of the sun-like stars near the sun also have planets orbiting them. b. Proving that none of the stars near the sun has planets orbiting them. c. Finding a planet located beyond the orbit of Pluto. d. Finding a meteorite whose age proved to be greater than 4.6 billion years. e. Proving that Mercury has the same uncompressed density as Earth.Choose the best answer b. Terrestrial planets are further from the Sun, more dense and have fewer moons c. Terrestrial planets are closer to the sun, less dense and have fewer moons d. Terrestrial planets are closer to the Sun, more dense and have fewer moons e. Jovian planets are closer to the Sun, less dense and have more moons f. Jovian planets are further from the Sun, more dense and have more moonsThe odd orbits of Nereid and Triton, which are moons of Neptune, indicate that these a. moons were captured. b. moons formed simultaneously with the planet from the same piece of the solar nebula. c. moons broke off from the rapidly rotating planet. d. moons formed as the result from a giant impact early in the planet’s history. e. orbits were disturbed long ago in an interaction with some other body.
- The dwarf planet Pluto was discovered in 1930. Since that time, which jovian planet has completed a full revolution around the Sun? a. Jupiter b. Saturn c. Uranus d. Neptune e. More than one of the above19 A planet is detected via the Doppler technique. The velocity change of the star is a measure of A The planet's size and density. B C D E The planet's mass and orbital distance. The planet's orbital period and eccentricity. The planet's mass and composition. The planet's size and orbital distance.The only other place in the solar system besides Earth where it rains and snows is a. Mars b. Titan c. Enceladus d. Triton e.

Why or why not? O Yes. That is why the outer planets are shown in a separate box. O No. The distances in the solar system are too great to produce a model accurate to distance that still has inner planets visible. O No. The outer planet distances are drawn to scale, but the inner planets need to be drawn farther from the sun to be visible. 1 4Which of the following statements is correct? a. The formation of planets stopped because the solar nebula got cooler c. The formation of planets stopped because the solar nebula ran out of planetesimals d. The formation of planets stopped because the solar nebula spinning was slowing down e. The formation of planets stopped because the young Sun's strong solar wind swept away material not yet accreted onto the planetsThe rings of Uranus were discovered a. during an occultation (an eclipse) of a star. b. during an eclipse of one of the moons by the rings. c. during an eclipse of Uranus by the rings. d. as Uranus and the rings passed behind Jupiter. e. by the Voyager 1 spacecraft.
