You decide to go on an interstellar mission to explore some of the newly discovered extrasolar
planets orbiting the star ROTOR. Your spacecraft arrives in the new system, in which there are
five planets. ROTOR is identical to the Sun (in terms of its size, mass, age and composition). From
your observations of these planets, you collect the following data:

The Tunguska asteroid is estimated to have had a diameter of 50 m, and to have produced an explosion equivalent to 10 megatons of TNT (1 megaton = 4.2 x 1015 joules). Assume that the asteroid was a sphere with density 2 g/cm3. Using the kinetic energy formula K = ½ mv2, where m is the mass and v is the speed, to estimate the speed of the asteroid. Assume that all kinetic energy is converted into the energy of the explosion.
Give your answer in km/s with one significant figure.

- (a) What is the difference between the forces on a 1.0-kg mass on the near side of Io and far side due to Jupiter? Io has a mean radius of 1821 km and a mean orbital radius about Jupiter of 421,700 km. (b) Compare this difference to that calculated for the difference for Earth due to the Moon calculated in Example 13.14. Tidal forces are the cause of Io’s volcanic activity.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_forwardLook at Figure 21-11. Which molecule(s) can escape from Earths gravity? From Mars? From Venus? Figure 21-11 Loss of atmospheric gases. Dots represent the escape velocity and temperature of various Solar System bodies. The lines represent the typical highest velocities of molecules of various masses. The Jovian planets have high escape velocities and can hold onto even the lowest-mass molecules. Mars can hold only the more massive molecules, and the Moon has such a low escape velocity that even massive molecules can escape.arrow_forward

What would it be like to visit such a location on Jupiter or Saturn? In what ways would the environment differ from that in the clouds of Earth?arrow_forward
- Present theory suggests that giant planets cannot form without condensation of water ice, which becomes vapor at the high temperatures close to a star. So how can we explain the presence of jovian-sized exoplanets closer to their star than Mercury is to our Sun?arrow_forwardWhat is the orbital velocity and period of a ring particle at the outer edge of Saturns A ring? (Hint: Use the formula for circular velocity, Eq. 5-1a. The formula requires input quantities in kg and m.)

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
- Which of these things did the Voyager spacecraft discover about Enceladus in the early 1980s, indicating that it is somewhat unusual among planetary bodies in our solar system? Check the TWO items that apply. a It has a thick atmosphere, made mostly of nitrogen. b It has the darkest, least reflective surface of all the known planetary bodies. c It is the brightest (i.e. most reflective) object in the solar system. d The entire surface is more heavily-cratered than any other body in our solar system. e Its surface is very smooth in some places.arrow_forwardWhat is the escape velocity in km/s from Venus' exosphere, which begins about 168 km above the surface? Assume the gravitational constant is G = 6.67 × 10-11 m3 kg-1 s-2, and that Venus has a mass of 4.9e+24 kg and a radius of 5800.0 km.arrow_forwardTitan has a very thick atmosphere of nitrogen gas at a surface pressure (P) of 150 kiloPascals (kg·m/sec2/m2 units). If pressure (P) is force per unit area, then the mass pushing down over 1 square meter of the surface will scale as P/g with g (1.352 m/sec2) being the surface acceleration due to gravity. Considering that the density of solid nitrogen is 1027 kg/m3, calculate the layer thickness of solid nitrogen that would result from freezing the atmosphere by dividing the density of nitrogen into the mass per m2? answer choices 108 meters 10.08 meters 1.08 kilometers 1.08 metersarrow_forward
