Calculate the mass of Callisto using a value for its density of 1.8 g/cm3. Convert your answer to units of kg, and compare to the mass of Ganymede given in Problem 5. (Notes: Density is mass divided by volume, and the volume of a sphere is
4. What is the escape velocity from the surface of Ganymede? Ganymede’s mass is 1.5 × 1023 kg and its radius is 2.6 × 103 km. (Hint: Use the formula for escape velocity, Eq. 5-1b. The formula requires input quantities in kg and m.)

- Title 1. Why are the belts and zones on Saturn less distinct than those on Jupiter? 2. Why do astronomers. Description 1. Why are the belts and zones on Saturn less distinct than those on Jupiter? 2. Why do astronomers conclude that none of the Jovian planets' rings can be left over from the formation of the planets? 3.

- Tutorial Based on the orbital properties of Uranus, how far across the sky in arc seconds does it travel in one Earth day? The average orbital radius is 2.88 x 109 km and the period is 84.0 years. (Assume Uranus and the Earth are at the closest point to one another in their orbits.) How many full Moons does this distance cover if the Moon has an angular diameter of 0.5 degrees? Part 1 of 4 We first need to determine how fast the planet is moving across the sky. If we know the period and the distance between the Sun and the planet we can calculate the velocity using: 2ar which will tell us how many kilometers the planet travels in a day if we convert the period into days. days = (P years' |days/year Pdays days Submit Skip (you cannot come back)arrow_forwardCalculate Uranuss Roche radius. Are all of Uranuss rings inside the Roche limit? Are any of the moons within the Roche limit? (Notes: The Roche limit is defined in Chapter 22. Necessary data are given in Celestial Profile: Uranus and Appendix Table A-11. The structure of the Uranian system is displayed in the Concept Art: Uranuss and Neptunes Rings.)arrow_forwardHow can Titan keep an atmosphere when Titan is smaller than airless Ganymede?arrow_forward
- Calculate the radius of Jupiters Roche limit for a satellite with density equal to the planet. Which of Jupiters moons is closest to the Roche limit? What might that tell you about the relationship between that moon and Jupiters ring?

When will Io run out of this gas at the current loss rate?arrow_forward
- Upload a PDF document that shows your work and solution. - Consider a moon of Uranus if Uranus is currently a distance of 2.08 billion km from Earth, then what diameter telescope would you need (use telescope-resolution formula = 1.22, where D is the telescope diameter) in order to clearly resolve the moon Titania in orbit around Uranus if the 47² )3 to relate moon has a period of orbit of T = 8.71 days? (use Kepler's 3rd Law T² = (GMrave T2 moon's period T to moon's orbital radius, r) The telescope only needs to resolve the small dot of the moon as distinct from the circle of light which is Uranus, so the orbital resolution is the angular size of the diameter of orbit of Miranda (use the arc-length formula 0 = 2 where d is the distance from Earth to Uranus). Take the mass of Uranus as 8.68 × 1025 kg, and the wavelength of light as 490 d nm.arrow_forwardFor the following questions, use the data found in Appendix D. Calculate the mass (in kg) of the Sun based on data for Uranus's orbit. (Use G = 6,67 x 10¬11 N. m²/kg? in your calculations. Round your answer to at least four significant figures.) x kg Compare the above calculated value with the Sun's actual mass.

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
