Matthew February 19, 2009 Period 4 Lets Go Into Space! The Solar System In the Solar System there is the Sun, then there are 9 planets. Which are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and last but not least Pluto. The Sun The Sun provides light for all the planets in the Solar System. All it is, is giant star made out of hydrogen and helium. Mercury The domed habitats on Mercury's surface are reflective for reasons of thermal management; other darker areas are concentrations of solar power collectors. Many of the deep caverns created by mining are used for agriculture using piped sunlight Venus You guys remember the missions to Venus? Well there are still remaining gaps filled with data! The Earth The Earth just isn't where we live but its where 6.2 billion people live. Earth is the only planet with life. Also the population is getting larger by the decade. Mars NASA really wants to be able to visit Mars as possible, but they have a lot of learning and packing to do before they do visit Mars! ExPresident George W. Bush Planned to send astronauts to the moon and land them on Mars by the year 2020! Jupiter Jupiter better known as the “gas giant”, is 11 times the Earths diameter, It is also 20% larger then Saturn, Making it the largest planet in the Solar System! Saturn Saturn is the second largest planet in the Solar System. Saturn's brilliant ring structure is made of water, ice, and rock; and have icy coatings in the form of innumerable small particles that range in size from about a centimeter to a kilometer. Uranus Uranus’ blue color is the result of absorption of red light by methane in the upper atmosphere. . There may be colored bands like Jupiter’s but they are hidden from view by the overlaying methane layer. Neptune There has recently been pictures taken of Neptune that show that there is an increase in Neptune's brightness in the southern hemisphere which is considered a change of seasons. Pluto (Dwarf Planet) Pluto was once a planet in our Solar System, but since August 24, 2006 it has been a dwarf planet. Not only is Pluto the smallest planet in the Solar System, but it is smaller then 7 of the Solar Systems moons! The End!
