Mass of Saturn Titan, the largest natural satellite of Saturn, takes 15.945 Earth days for one complete orbit. The semi-major axis of Titan’s orbit around Saturn is 1.22 = 106 km. Find the mass of Saturn. Assume that the mass of Titan is much less than the mass of Saturn.

Meteor Speeds Estimate the speed that a meteoroid attains when it ablates as a meteor in Earth’s upper atmosphere (see Figure 11-15). Use the following simplifying assumptions in obtaining the estimate: • The meteoroid started from rest at such a great distance from Earth that the two can be considered to have been infinitely far apart. • The influence of all other objects (e.g., the Sun and the Moon) is negligible. • Earth’s upper atmosphere does not significantly slow the meteoroid up to the time of ablation, about 90 km above the surface.
