Put another way, in order to stop being needy and desperate, itâs essential for you to think in terms of abundance. To see this world as a world full of opportunities, in which when one door closes, another one opens. It is very much true.
Earth and the other three inner planets of our solar system (Mercury, Venus and Mars) are made of rock, containing common minerals like feldspars and metals like magnesium and aluminum. So is Pluto. The other planets are not solid. Jupiter, for instance, is made up mostly of trapped helium, hydrogen, and water. In our solar system, the four gas giants are Jupiter, Saturn, Neptune, and Uranus. Planets with their relative sizes to scale. The tiny bluish dot at the lower left is Earth.
It isn't that the outer planets are made out of just gas. They have rocky cores just like the ones inside the inner planets. Gas is not very dense when it is in the form of huge shapeless clouds floating around a sun. Solar winds easily push the particles of gas farther out into space.herefore, the inner planets are composed of rock and metal. However, by the time the wind hit the outer planets it became weaker and the gravitational attraction of the rocky protoplanets was strong enough to hold on to the lighter elements. 6 people found this useful.
