On December 25, 2004, the Huygens probe separated from the Cassini spacecraft orbiting Saturn and began a 22 day journey to Saturn’s moon Titan, on whose surface it landed. Besides the data in Appendix F, it is useful to know that Titan is 1.22 * 10^6 km from the center of Saturn and has a mass of 1.35 * 10^23 kg and a diameter of 5150 km. At what distance from Titan should the gravitational pull of Titan the gravitational pull of Saturn?
The tidal acceleration due to the moon at the surface of the earth is approximately
2.44×10^−5 ms−2
If the moon was closer to the earth by a factor of 0.9. What then would the tidal acceleration be.
