What is the frost line in the solar nebula? Explain how temperature differences led to the formation of two distinct types of planets.
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.

Why do astronomers conclude that none of the Jovian planets' rings can be left over from the formation of the planets? 3. How can a moon produce a gap in a planetary ring system?arrow_forwardMission to Titan: Titan is the largest of Saturn’s moons and the only moon in the Solar System that possesses a dense atmosphere and large liquid bodies (seas or lakes) at its surface. For these and other reasons, many exobiologists think that Titan is the most likely place in the Solar System beside Earth where life might exist. NASA is considering sending a 600 kg space probe into orbit around Titan in order to map its surface. This would be followed a few years later by a 320 kg robotic lander that would land on the surface of Titan in order to look for life. a) What would be the space probe’s velocity and orbital period if the probe were to orbit at an altitude of 70 km above the surface of Titan? b) What force would the lander’s thrusters need to produce in order to allow the lander to hover just above the surface of Titan.arrow_forward

A The temperature in this portion of the solar nebula was just right to prevent rock from sticking together. B C D There was too much rocky material to form a terrestrial planet, but not enough gaseous material to form a jovian planet. There was not enough material in this part of the solar nebula to form a planet. Gravitational tugs from Jupiter prevented material from collecting together to form a planet. E A planet once formed here, but it was broken apart by a catastrophic collision.arrow_forwardFor 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.arrow_forward
