- A lot of asteroid and comet dust collides with Earth's atmosphere everyday. Assume that 500 tons of mass is added to Earth daily from the millions of meteors that enter our atmosphere. Estimate the time it would take for the Earth's mass to increase 0.2% with this impact rate. Is this mass accumulation significant to Earth as a planet.Calculate the Roche limit of the Earth-Moon system.The Mariner 10 spacecraft went past Venus for a gravity assist maneuver, in order to slow down with respect to the Sun and to to Mercury speed up with respect to the Sun and go to Mercury allow it to travel over the Sun's polar regions "slingshot" around Venus and come back home to Earth

(a) Calculate thermal escape times for H, He, and H2O on Mars with exosphere temperatures of 210 K and 1000 K.

- 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?Calculate the Roche radius (in km) for Uranus. The diameter of Uranus is 5.11 ✕ 104 km.Planetary scientists are excited about the possibility that some of the moons in the outer solar system might have a global subsurface ocean of liquid water. It's uncertain whether or not Jupiter's moon Callisto has a subsurface ocean, but some scientists think it might. Let's imagine that a short distance below the surface, Callisto has a water layer 20,000 meters thick. Callisto has a radius of 2.410x106 meters. Earth has a radius of 6.378x106 meters, and its oceans are equivalent to a layer of water 3000 meters thick all over the surface of the planet. Which of the following is an accurate comparison of the Earth’s amount of liquid water with this estimate of the amount of water Callisto might have? Group of answer choices If this scenario is correct, Earth and Callisto have roughly the same amount of liquid water. If these scientists are right, Callisto has about one-sixth as much liquid water as the Earth does. If these scientists are right, Callisto has about 11 times as…
- 4) Science fiction movies often portray asteroid belts as crowded, dense regions that require spaceships to maneuver quickly to get through them. In this problem, we will calculate the fraction of volume in an asteroid belt that is actually occupied by asteroids. a) If there are 300,000 large asteroids between 2 and 3 AU from the Sun, and each asteroid is assumed to be spherical with a radius of 100 km, determine the total volume occupied by asteroids in this region. Recall that the volume of a sphere is given by the equation V = 4TR³ /3. b) Let's assume the region in which these asteroids orbit is an annulus with an inner radius of 2 AU, an outer radius of 3 AU, and a thickness of 2Ro. Determine the volume of this region. Recall that the area of a circle is given by the equation A = TR². Here are two conversions that you'll need: 1 AU = 1.496 × 108 km and 1 Ro = 6.955 × 105 km. c) What is the ratio of the volume occupied by asteroids to the volume of the asteroid belt (i.e., the…Explain why a massive, cool planet is more likely to have a thick atmosphere than is a less massive, hot planet.Why is the composition of a comet typically dominated by volatile materials (frozen ices)? choose one of the following: a. rock and metal could not condense out of the solar nebula at extreme distances from the sun b. most of the metal in the solar system is locked up inside the terrestrial planets c. metals are not stable in the outer solar system d. elements that form ices (as opposed to rock & metals) are more abundant in our solar system
