- Enceladus is a moon of Saturn. What unique feature does it possess? which is the correct answer? Cryovolcanism, where water erupts instead of silicate rock A dense system of rings An atmosphere thicker than Earth's Internal heating due to radioactivity Has an orbit inside Saturn's ringsThe Moon's mass is 1/80 that of Earth, and the lunar radius is 1/4 Earth's radius. Based on these figures, calculate the total weight on the Moon of a 100-kg astronaut with a 50-kg space- suit and backpack, relative to his or her weight on Earth.In the case of Mars, the time from opposition to the eastern quadrature is 107 days,and the sidereal period of Mars is 686.98 days, Calculate its orbital radius in the unit ofAU.
- Imagine that Earth had two identical Moons, following the same orbit but staying 180° apart. What effects would this have on the ocean tides experienced on Earth?How deep would be the eclipse caused by Jupiter transiting in front of the Solar disk, as observed from a distant star?Given that Earth is about 4.6 billion (4.6 x 10%) years old, how many precessional cycles have occurred?
- If G is given by 6.67 X 10-11 and the mass and radius of the Moon are 7.35 x 1022 kg and 1738 km, respectively, what is the value of g on the surface of the Moon in m/sec2? Remember that g=GM/R2 in m/sec2.A spacecraft starts out in an eastward-moving circular orbit around Jupiter. It then burns its engines and increases its speed beyond Jupiter's escape speed - and it does this while it's over Jupiter's night hemisphere. Which of the following might be its destination? Uranus the Sun Mars EarthAt perigee, the Moon is 365,000 km from Earth. At apogee, it is 407,000 km away. How many times larger does the Moon appear to us during perigee than at apogee? The linear diameter of the Moon is 3,480 km.
