Mission to Titan. On December 25, 2004, the Huygens probe separated from the Cassini spacecraft orbiting Saturn and began a 22-day journey to Saturn’s giant moon Titan, on whose surface it landed. Besides the data in Appendix F, it is useful to know that Titan is 1.22 × 106 km from the center of Saturn and has a mass of 1.35 × 1023 kg and a diameter of 5150 km. At what distance from Titan should the gravitational pull of Titan just balance the gravitational pull of Saturn?

- Let gM represent the difference in the gravitational fields produced by the Moon at the points on the Earths surface nearest to and farthest from the Moon. Find the fraction gM/g, where g is the Earths gravitational field. (This difference is responsible for the occurrence of the lunar tides on the Earth.)arrow_forwardCalculate the effective gravitational field vector g at Earths surface at the poles and the equator. Take account of the difference in the equatorial (6378 km) and polar (6357 km) radius as well as the centrifugal force. How well does the result agree with the difference calculated with the result g = 9.780356[1 + 0.0052885 sin 2 0.0000059 sin2(2)]m/s2 where is the latitude?arrow_forwardModel the Moons orbit around the Earth as an ellipse with the Earth at one focus. The Moons farthest distance (apogee) from the center of the Earth is rA = 4.05 108 m, and its closest distance (perigee) is rP = 3.63 108 m. a. Calculate the semimajor axis of the Moons orbit. b. How far is the Earth from the center of the Moons elliptical orbit? c. Use a scale such as 1 cm 108 m to sketch the EarthMoon system at apogee and at perigee and the Moons orbit. (The semiminor axis of the Moons orbit is roughly b = 3.84 108 m.)arrow_forward
- What is the orbital radius of an Earth satellite having a period of 1.00 h? (b) What is unreasonable about this result?arrow_forward(a) In order to keep a small satellite from drifting into a nearby asteroid, it is placed in orbit with a period of 3.02 hours and radius of 2.0 km. What is the mass of the asteroid? (b) Does this mass seem reasonable for the size of the orbit?arrow_forwardA planet has a mass of M1, a radius of R1, and a density of ρ1. A second planet has a mass of M2, a radius of R2, and a density of ρ2. This problem will explore the relationships between the surface gravities (g1 and g2) of the planets depending on the relative sizes of their masses, radii, and densities. a) Assume that planet 2 has X times the mass of planet 1, or M2 = XM1. The densities of both planets are the same. Write an expression for the ratio of the surface gravity of planet 2 to planet 1 in terms of X. b)Suppose now the radius of the second planet is Y times the size of the radius of the first planet, or R2 = YR1. Write an expression for the ratio of the surface gravities, g2/g1 in terms of Y assuming the densities are the same. c) Suppose now M2 = 8M1 and ρ2 = 8ρ1. What is the ratio of g2/g1 now (here we want the actual number; because you are writing a ratio, the number will be unitless)? d) Now suppose R2 = 10R1 and ρ2 = 10ρ1. Find the ratio of g2/g1 (again as a number…arrow_forward
