Which of the following statements accurately describes our current understanding of the solar system? a. There are no metals in the solar system beyond Jupiter and its orbit. b. Terrestrial worlds are so small because their large atmospheres were stripped away in time by Jupiter. c. Jupiter and Saturn are made of strictly a combination of hydrogen and helium, and both objects lack a planetary core. d. Various ices can contribute to the mass of planetary cores if we are at a great enough distance from the sun.
1. Suppose a 70, 000 km radius planet is 5 AU away from the sun (use 1 AU = 150 million kilometer).

Imagine that you visit a planet orbiting another star and discover that it is heavily cratered, but its small moon is nearly crater free. Why would that be a surprise? Speculate about what might have happened to those objects.
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? Group of answer choices Other planetary systems should be identical to our own. Planetary systems should be very rare. Most stars should have one or two planets, but not more. Planetary systems should be common. 15. Which of the following statements best describes the accomplishments of these three people?

1. Which of the outer planets have compositions dominated by the "ices" ingredient? Check the correct two. 2. Which of the outer planets have compositions dominated by the "gases" ingredient? Check the correct two. 3. Most of the spaceflight missions to the outer planets have been flyby missions, but two of them were orbiters. Which of these two spacecraft orbited giant planets? Check the correct two. (Hint: An orbiter might do a flyby of one planet and then go on to orbit a different planet.) 4. Jupiter's mass is how many times larger than the Earth's? Just type a number, no words or any other extra stuff. 5. Which of the outer planets has extreme seasons, with its rotational axis being tilted so much that it is practically in the plane of its orbit?
how do you compare us with people from the moon. Explain?
Venus is very bright and reflective because of its a. high surface temperatures b. large number of active volcanoes c. thick cover of sulfuric-acid clouds d. planet-wide oceans 2. The first six Soviet Venera landers failed to return pictures and data from Venus because they all a. got excessively corroded during their passage through Venus's sulfuric-acid clouds b. fell too slowly through Venus's thick atmosphere and got fried before landing c. missed their rendezvous withe Venus because of errors in their orbits d. got cancelled due to technical or budgetary problems
For which of the following reasons (select all that apply), is it useful/important to send rovers to other planetary bodies in our solar system? a. More direct probes of the planetary surface are possible to detect signs of the building blocks of life. b. Rovers/landers can be outfitted with various tools and equipment that can be used to inform of us of the geological histories of each of the planets they visit. c. Rock samples can be used to calibrate our estimations of the age of the solar system. d. The data collected can help improve our understanding of the evolution/development of our solar system. e. The engineering innovations developed to produce successful/viable rovers and landers on other planets can help lead to developments in the technology used here on Earth that may have taken far more time to develop without the limitations provided by space travel to foreign worlds.
