  1. Venus By: Ansley Maness, Hannah Hernandez, James Butler

  2. Terrestrial Planet • Tilt: 177.3˚ • **180˚-177.3˚= 2.7˚, so Venus is almost completely upside down. • Rotates clockwise, (technically counterclockwise because it’s upside down) • 108,200,000 km from Sun Venus- Basic Properties

  3. Length of day: fully rotates every 116 Earth days • Length of year: completes orbit of Sun every 224.65 Earth days. • Constant temperature: 735˚K (865˚F) Venus- Basic Properties

  4. Mass: 81.5% of Earth’s mass • Density of Venus: 5250 kg/m3 • Density of Earth: 5520 kg/m3 Venus- Basic Properties

  5. Venus- Basic Properties • Believed to have similar internal structure to Earth: core, mantle, crust • Made of rock and metal • Partially liquid core

  6. Venus- Basic Properties • Lower internal pressure • No plate tectonics • Lacks internal magnetic field (due to slow rotation)

  7. Very thick and dense atmosphere, 92x as dense as Earth’s • 96% CO2, 3.5% N2 • Relatively smooth surface • Large number of volcanoes • No ringsor moons Venus- Atmosphere/Surface

  8. Discovered by ancient civilizations, because it’s visible with naked eye • First planet to be reached by a probe • Mariner 2 (1962): flew within 34,400 km of surface • Venera 7: first probe to land on Venus • Magellan (1989): collected radar images of 98% of Venus’s surface Venus- History
