Chapter 11, Problem 23E
The water clouds believed to be present on Jupiter and Saturn exist at temperatures and pressures similar to those in the clouds of the terrestrial atmosphere. 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?

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.
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…
What is the escape velocity is km/s from Jupiters exosphere, which begins about 993 km above the surface ? Assume the Gravitational constant is G= 6.67 x10-11m3 kg-1s-2, and that's Jupiter has a mass of 1.8999999999999998e+27kg and a radius of 68.0 x103km

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_forwardWhy do the upper levels of Neptune’s atmosphere appear blue?arrow_forwardHow many times more pressure exists in the interior of Jupiter compared to that of Earth?arrow_forward
- What is the primary source of Jupiter’s internal heat?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_forwardWhat allows moons of Jupiter and Saturn to have liquid interiors?arrow_forward
- A new Terrestrial planet has been discovered orbiting a nearby Sun-like star. Astronomers have obtained spectra of this planet and determined that the atmosphere is composed of roughly 99% CO2, and the remaining 1% is mostly N2 and is very thin compared to Earth's atmosphere. Briefly describe how the planet could have developed such an atmosphere.arrow_forwardThe fraction of the energy flux received which is reflected into space is the albedo of Venus, av, which is about 0.76. The fraction of the energy flux which is absorbed is then (1-av) = 1. - 0.76 = 0.24. So the amount of energy actually absorbed by Venus in each second is Lv = (1-av)Ev. Lv = (1-av)Ev = ___________________ ergs/s And next calculate the effective temperature of Venus: Tv4 = (Lv/(4pdv2))/s = Lv/(4spdv2) = __________________ K4 and taking the square root of Tv4 twice in succession we get the effective Temperature Tv: Tv = [Lv/(4spdv2)]0.25 = _________________ K Calculate Venus' emittance assuming that the Venus' actual temperature, Tvr, is 472o C = 745 K: ev = Lv/(4pdv2s Tvr4) = __________________ .arrow_forwardNASA Scientists want to measure the current distance between two of Jupiter's Moons, Ganymede and Europa. They set up a laser on the surface of Ganymede, shine it at a mirror on the surface of Europa and measure how long it takes for the laser light to return to a detector on the surface of Ganymede. They calculated the current distance between the two moons to be 787 million meters. How long did it take the light to make it to Europa and back? *Give answers to at least three significant figures.
