  1. Venus’ symbol By. Jiweon Moon Venus

  2. History of Venus’ Name Venus is named for the ancient Roman godness of love and beauty. (Venus is the Roman counterpart to the Greek Godness Aphrodite.) It is believe Venus was named for most beautiful of the ancient gods because it shone the brightest of the five planets known to ancient astronomers

  3. Appearance /discovery of Venus • Venus is almost light brown and gold color. It has marbling shapes on it’s surface which is actually the clouds. Also, it’s very bright viewed from the Earth. • Discovered by the Ancients • Discovered on unknow date

  4. Distances/Measurements • Order from the Sun: Second • Distance from the Sun: 108.1 km • Distance from the Earth: 41.4 km • Mass: 4.8673x10^24 kg • Volume: 9.28415x10^11 ㎦ • Density: 5.243 g/㎤ • Gravity: 8.87 ㎨ • Venus will sink in water because the density of water is 1.0 g/㎤ and if an object is more dense than water, it sinks.

  5. Orbit and Rotation • Takes 225 Earth days to orbit around the Sun • Takes 243 Earth days to rotate on its own axis

  6. Atmosphere/Composition • Venus is rocky planet, and it’s solid surface is cratered and volcanic landscape it has very thick atmosphere • Its atmosphere is mostly made out of carbon dioxide (CO2), and nitrogen (N2) with clouds of sulfuric acid (H2SO4) droplets • It’s internal compositions are core, mantle, and crust • ~96.5% carbon dioxide • ~3.5% nitrogen • 0.015% sulfur dioxide • 0.007% argon • 0.002% water vapour • 0.0017% carbon monoxide • 0.0012% helium • 0.0007% neon

  7. Weather/Temperature/Water • Extremely hot (all through the year) • Humid • High: 480°C • Low: 440°C • Range: 40°C • It has only trace amounts of water have been detected in the atmosphere

  8. If a human traveled to Venus… That human would choke by the atmosphere of Venus. Even he/she land safely at Venus, it’s volcanically active so it might be very dangerous. Venus is too hot for certain life to live there and it rarely have water. So human might choke, burn, or die by the thirstiness.

  9. Something special about Venus • It’s the brightest planet • More than 40 spacecraft went to Venus. ex) NASA's Magellan mission during the early 1990s used radar to image 98 percent of the surface, and the Galileo spacecraft used infrared mapping to view both the surface and mid-level cloud structure. • Retrograde
