We are all familiar with the various elements that make up our own little world. Of course, there is the air that we breath and need to survive, which is made up of about 78% nitrogen, 21% oxygen, and a small amount of other elements (yes, there is more nitrogen than oxygen in the air). Then, of course, our planet itself has a relative abundance of water. Earth's oceans cover much of the planet, making up some 70% of the Earth's surface, and as a fun aside, our waters have an average depth of 2.5 miles (4 kilometers). We also have the rocky material, which is made up of iron, oxygen, silicone, and trace amounts of other elements. But what about the other planets in our solar system? What are they made of?
Well, since the Earth is the only known planet to harbor life, if probably isn't too surprising that conditions (and constituents) of the other planets are far different than what we find on our own little world. In fact, it wouldn't take very long to die on other planets in our solar system. On most worlds, you could only survive for seconds.
