How many impacts would you expect to strike a 100m2 region in one hour during Earth’s formation, assuming that Earth grew to its present size in 10 million years from particles averaging 100 grams each? (Hint: Assume that Earth had its current radius of 6378km.) (Notes: The surface area of a sphere is 4pir2 ; 1yr=3.2x107 .)
a. About 1300.
b. About 13 .
c. About 13,000.
d. About 130
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?
The asteroid Hygiea has a mass of 8.67 x 1019 kg and an average radius of about 216 km (2.16 x 102 km). What is its escape velocity (in m/s)? (Hints: Use the formula for escape velocity,

- 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.arrow_forwardPretend you are a NASA executive or a legislator. Design a new mission in our solar system. Pick any object in the system and decide whether you want to send an orbiter, a lander, a rover, some combination or those, a manned mission, or something else. What interests you about this object? What science questions can we answer? In basic terms, what kind of scientific instruments might you want to include on your mission? Justify your decisions with what you know about the scientific method, astronomy techniques, and the object itself from this class.arrow_forwardWe believe that chains of comet fragments like Comet Shoemaker-Levy 9’s have collided not only with the jovian planets, but occasionally with their moons. What sort of features would you look for on the outer planet moons to find evidence of such collisions? (As an extra bonus, can you find any images of such features on a moon like Callisto? You can use an online site of planetary images, such as the Planetary Photojournal, at photojournal.jpl.nasa.gov.)arrow_forward
