A. Terrestrial 1) Made up of a metallic core, and a rocky mantle 2) Has a thin crust 3) Has many volcanoes B. Atmosphere 1) Very thick atmosphere containing mostly carbon dioxide 2) Has a high atmospheric pressure of 90 atm C. Moons 1) Doesn’t have any moons 2) The reason why is unknown, though it is believed it has something to do with its upside down rotation D. It is about the same size as Earth. It has a diameter of 12,104 km compared to Earth's 12,742 km diameter E. Its distance from the sun is approximately .72 AU's F. Its orbit around the sun is 224 earth days, and its days are 117 days on Earth G. The precipitation on Venus is composed of sulfuric acid, which would burn your face. It has an average daily temperature of 400 degrees Celsius. It is believed to have once been habitable billions of years ago, but that is not a known fact. H. There has been 22 missions made to Venus by NASA the EPA, and Russia. There are currently 6 future missions planned for Venus.
A. Terrestrial 1) Made up of a metallic core and rocky mantle 2) Has a thin crust layer 3) Has water, and other nutrients for life B. Atmosphere 1) Roughly 100 times thinner than Earth's atmosphere 2) Mainly made up of Carbon Dioxide 95%, it also contains 2.7% of nitrogen, and 1.6% of Argon 3) .007 atm C. Moons 1) There are 2 moons around Mars 2) They are believed to be asteroids that crashed into Mars and fell into orbit, like our moon D. Mar's is smaller compared to Earth, it's diameter is about 53% the size of Earth E. Its distance from the sun is 1.52 AU's F. One year on Mars is 687 days on Earth, and one day is 24 hours and 37 min G. There are many active volcanoes on Mars; the poles have ice sheets made of carbon dioxide. There are sign of atmosphere on Mars in the past, and there has been fossilized bacteria found, which suggests there may have once been life on Mars. H. Mars has had 31 missions in the past, and currently in 2013 has 5 active missions. Jupiter A. Jovian 1) Mainly made up of gases 2) Has a small rocky core 3) Has rings B. Atmosphere 1) Huge atmosphere, mostly made up of hydrogen and helium. 2) The atmospheric pressure is 10 times Earth's, so it's 10 atm C. Moons 1) It had 67 moons 2) It has so many moons because of its enormous gravity, any asteroids the flow past Jupiter are pulled into orbit. D. Jupiter has a diameter that is 120 times larger than Earth's. E. Jupiter's distance from the sun is 5.18 AU's F. It takes Jupiter 12 Earth years to orbit the sun, and a day on Jupiter is only 9 hours and 55 min G. The great red spot on Jupiter is a storm that has been going on for hundreds of years. Its moon Europa is the same size
