The Great Red Patch is the term given to the enormous red area on Jupiter's surface. Are there any predictions on how long it will take the planet to complete its rotation?

3. Why are the inner planets made of denser materials than the outer planets?

How long (in Earth-Years) does it take Saturn to orbit the Sun? Use these values of (average) distance to the Sun. Venus: .72 A.U. Saturn: 9.5 A.U. Give your answer in (Earth) years to the correct number of significant figures.

The synchrotron radiation (radio waves) that astronomers first observed from Jupiter in the 1950's comes from a. deep within Jupiter, in the metallic hydrogen layers b. high speed electrons spirling around the planet's strong magnetic field c. the upper-atmosphere clouds that more quickly near the equator of the planet d. the Red Spot with its tremendous friction

1. Which of the outer planets have compositions dominated by the "ices" ingredient? Check the correct two. 2. Which of the outer planets have compositions dominated by the "gases" ingredient? Check the correct two.  3. Most of the spaceflight missions to the outer planets have been flyby missions, but two of them were orbiters. Which of these two spacecraft orbited giant planets? Check the correct two. (Hint: An orbiter might do a flyby of one planet and then go on to orbit a different planet.) 4. Jupiter's mass is how many times larger than the Earth's? Just type a number, no words or any other extra stuff. 5. Which of the outer planets has extreme seasons, with its rotational axis being tilted so much that it is practically in the plane of its orbit?

Calculate the weight of a 75.6 kg astronaut on the surface of Mars at the equator. See p. 273 of your textbook for Mars' mass and equatorial radius. 75 Clu m U

20 Approximately how many other planetary systems have been discovered to date? A Tens of thousands B) Tens C Hundreds D Thousands E Millions

Although Deimos is smaller than Phobos, Deimos has more debris on its surface. This difference in the two moons is probably the result of   a. the greater number of impact craters on Deimos.   b. Martian gravity, which is strong enough to pull debris off the surface of Phobos.   c. the lack of volcanic activity on the surface of Phobos.   d. the comparatively weaker gravity on Deimos.   e. the slower rotation rate of Deimos on its axis.

1. The diameter of the Sun is equal to 1.392*10^9 m, and the distance from the Sun to Saturnis equal to 9.5 AU. Suppose you want to build an exact scale model of the solar system,and you are using a volleyball with average diameter of 21 cm to represent the Sun. a) In your scale model, how far away would Saturn be from the Sun? Give your answer inmeters.b) The actual diameter of Saturn is 116,460 km. What would be Saturn’s diameter in yourscale model? Give your answer in centimeters.
