Outer\Gaseous+Planets


 * __LOST IN SPACE project: You have a ton of information about the planets now. Nice job! Now, I want you to think about being lost in these outer planets! Imagine you took off in your space van and had to survive out in these planets. Where would your best five places be to survive and what would your worst five places be.__** __**Once you decide where, be sure to include why. I'm look for physics and chemistry reasons why, so be sure to mention those.**__ **__Be sure you only use the outer planets. You have a lot of info to work from.__**

5 Top Characteristics:


 * Neptune** - It has a great dark spot that can travel at supersonic speeds. It is covered in an "ocean" that moves at supersonic speeds. It is made up of a liquid rock core. It has thin rings that when rolled up in a ball, would only be a couple of miles across. As they are right now they cover 77,500 miles. It is blue because of methane on its surface and in its atmosphere.


 * Uranus** - It is the only planet that rotates on its side. It has 11 rings and 29 moons! It has a liquid rock core and is blue because of methane; just like Neptune. These two planets are so alike that they are often called sisted planets.

It is the 6th planet from the Sun. Saturn's volume is 8.2713 × 1014 km³ Its mass is 5.6846 × 1026 kg and its density is 0.687 g/cm³ Its year is about 10,832 Earth days or 29.7 Earth years. Its day is about 10.57 hours. Saturn's chemical composition is Hydrogen (75%), Helium (25%), with traces of water, methane, ammonia and rocky matter. It is estimated that Saturn has a small rocky core surrounded by mostly hydrogen and helium. The atmosphere of Saturn is 96.3% molecular hydrogen and 3.25% helium. Saturn's wind are among the solar systems fastest, with Voyager estimating them to be 500 m/s. Seasons on Saturn change very slowly, once every 10 years, with no difference between seasons. Saturn has been known since ancient times. We have observed Saturn with our eyes, ground base telescopes, and probes telescopes in space. Hindus, Greeks, Jewish people, and Romans have studied Saturn. Giovanni Cassini, William Herschel, and Christain Huygens are also scientists who studied it. Currently N.A.S.A. and other national space programs study Saturn.
 * Saturn** - It is 9.58 AU's from the Sun on average.

It is the 5th planet from the Sun. V = 1.43128×1015 km³, M = 1.8986×1027 kg, D = 1.326 g/cm³ Its year is about 4331.5 Earth days or about 11.86 Earth years. Its day is about 9.9 hours. Jupiter's chemical composition is 90% hydrogen, ~10% helium, traces of methane, etc. Jupiter is thought to consist of a dense core with a mixture of elements, a surrounding layer of liquid metallic hydrogen with some helium. The atmosphere on Jupiter is 88–92% hydrogen and 8–12% helium. Jupiter's most noticable from of weather, is clouds, with the Great Red Spot being the main feature. Like Saturn, there are no differences in its seasons and the seasons change once every three years on Jupiter. Jupiter was discovered by ancient astronomers. We have observed it with ground based telescopes and probes. Robert Hooke, Giovanne Cassini, and Galileo Galilei are only a few of the scientists who have researched Jupiter. Like most other planets, Jupiter is currenly being observed by N.A.S.A. and other national space programs.
 * Jupiter** - It is 5.2 AU's from the Sun on average.

​ This is pretty good Jason. I got a bit confused on the size of Earth, but I think I worked it out. Nice use of props and I even like the big extraterrestrial cat! Keep going on the Trouble with Space Vans. Score=5

The five places I would WANT to go in our outer solar system would be:

1. Europa because it has liquid water, is relatively close to Earth, and its atmosphere is compromised mostly of oxygen.

2. Ganymede wound be my second choice because it has a mostly oxygen atmosphere, and it has water. Even though its water is in the form of ice we could be able to work around this, having water of any kind is great! 3. Triton would be my third pick because it is composed 15 - 35% of water/ice. Even though Triton does not have very much oxygen we might be able to find a way of efficiently separating water into oxygen and hydrogen.

4. Callisto would be my fourth pick because it also has water (in the form of ice). Just like Triton we could maybe devolope a way of separating water. Another way to help give us oxygen would be to use plants which would probably survive because we have detected organic compounds on Callisto's surface. The plants could help mildy transform the mostle CO2 atmosphere.

5. My fifth pick would be Titan, it has water on it even though it has no oxygen we would hopefully be able to develope a way to overcome that obstacle.

The five places I would NOT want to go to in our outer solar system woulud be:

1. & 2. My first and second picks would be interchangeable because they are __both__ horrible. Jupiter and Saturn both have very little water and __no__ oxygen.

3. Io has very little oxygen and a very small amount of water.

4. & 5. Even though Rhea and Dione both have an almost completely solid ice core it would be virtually impossible to melt the ice because Rhea's max temperature is -174 Degress Celcius and Dione's max temperature is -186 Degress Celcius. Both of these moons have no atmosphere/oxygen.


 * __Nice work! I'm bummed that you won't have a chance to do tie-dye with me this coming week, but if you check out my website it can show you how to do it. If you choose to do it at home follow the instructions and do the reflection that's listed there and I'll give you extra credit.__**
