Pluto’s moon Charon orbits Pluto every 6.4 days,The weaker gravity of Mars means that 1 bar of pressure on Mars would be the pressure exerted by about 25,000 kilograms pushing down on each square meter of the martian surface. Based on this approximation, the atmospheric pressure on Mars (see Table 8.3), and the size of Mars, estimate the total mass of Mars’s atmosphere. Compare to Earth’s atmospheric mass from Problem 50. on an elliptical path with an average distance of 19,700 kilometers. Calculate the combined mass of Pluto and Charon. Compare this combined mass to the mass of Earth, which is about 6 × 1024 kg. Can you determine the individual masses of Pluto and Charon from the given data? Explain
