Titan is the largest moon of Saturn, the second-largest in the Solar System and larger than any of the dwarf planets of the Solar System. atmosphere is made up of gases in all planets. The inner planets (Mercury, Venus, Earth, and Mars) are relatively small rocky planets made up mostly of silicate minerals and iron and nickel metal. They are expected to have formed closer to their parent stars, where the protostellar nebula was denser. d. hydrocarbons b. From deep below the soil at Earths polar regions to Plutos frozen heart, ice exists all over the solar systemand beyond. Most asteroids are irregularly shaped, though a few are nearly spherical, and they are often pitted or cratered. Exoplanets twice the size of Earth and larger may be rocky as well, but those are considered super-Earths. a. Uranus a. gas, solid, liquid d. molecular hydrogen and helium. The fact that Jupiter's radius is contracting at a rate of 1 mm/yr results in Jupiter is primarily composed of just two elements: hydrogen and helium, along with trace amounts of other chemicals such as water, sulfur, methane, and ammonia. b. Saturn The closer proximity of Venus to the Sun, and the resultant higher temperatures, may have led to the loss of most of the water from that planetmost likely through the dissolution of water into hydrogen and oxygen. Venus is believed to have an iron core surrounded by a mantle and crust composed of rock and metal. 3. To our eyes, the sky would be hazy and red because of suspended dust instead of the familiar blue tint we see on Earth. Both water and carbon dioxide clouds are observed on Mars, and it has well-defined seasons. Venus atmosphere, like Mars, is nearly all carbon dioxide.
