Venus By Taylor, Morgan, and Breeze.
About Venus • Venus is named after the Roman goddess of love and beauty. • Venus rotates on it’s axis every 243 earth days. • Venus’ mean radius is 3,760. • http://science.discovery.com/video-topics/space-videos/space-school-venus.htm
Appearance • Venus is the brightest planet in the solar system. • Bright due to it’s reflective clouds. • Venus has no moons. • Venus is mostly spherical and doesn’t bulge at the poles like most planets.
atmosphere • Venus is the hottest planet in the solar system because it’s dense atmosphere traps in heat. • “Runway version of the greenhouse effect” • Atmosphere contains Carbon dioxide. • Space probes only lasted an hour because of the heat. • Atmosphere rotates faster than Venus rotates itself.
Atmosphere • The clouds go around the planet every four Earth days, propelled by hurricane force winds. • Winds on surface are much slower than winds in the atmosphere. • Temperature is 870 degrees Fahrenheit. • Hot enough to melt lead. • Escape velocity is 10,400 miles per second.
Surface • Venus’ surface pressure is 90 times more than Earth’s. • Venus is extremely dry due to extreme heat. • Surface is flat, smooth planes marred by thousands of volcanoes. • Surface has few impact craters, indicating Venus’ youth. • Lava flows create large canals over 300 thousand miles long.
Surface • Six mountainous regions that make up 1/3% of Venus’ surface. • Maxwell mountains are 540 miles wide and 7 miles above the average surface area. They lie on the continent of Ishtar Terra, which is about the size of Australia. • Crowns that are ring-like structures and are hot material beneath the crust that rises up. • Tiles, which are raised areas in which ridges and valleys have formed.
Relation to solar system • Venus is the second planet from the sun. • Is 67, 237, 910 miles from the sun. • Venus rotates clockwise, which is opposite of the other planets. • Venus takes 225 days to rotate the sun. • Venus cannot generate magnetic fields like Earth. • Venus is considered Earth’s twin, having only a 638km difference in diameter.
Clouds & Weather • The clouds go around the planet every four Earth days, propelled by hurricane force winds. • Clouds contain sulfuric acid. • ‘Venus Express’ found evidence of lightning on Venus. • 220 mile per hour winds. • Scientists found traces of water on Venus. • Hurricane force winds on Venus are growing stronger.
Missions to Venus • Most wildly explored planet in the solar system. • ‘The Messenger’, which is ongoing right now, is circling Venus and Mercury. • A past mission is the ‘Venus Express’. • A future mission to Venus includes the ‘Bepicolumbo’, which is being sent out in 2015. • Another future mission is the ‘Climate Orbiter’, which is being sent out again to Venus after a previous failure. • http://www.cleanvideosearch.com/media/action/yt/watch?v=LYK9rbVpOcI
Assessment • Why is Venus the brightest planet in the solar system? • Why is Venus the hottest planet in the solar system? • What continent are the Maxwell Mountains located on? • What’s different about the rotation of Venus in relation the most other planets? • What’s happening with the strong winds on Venus as time goes on? • What satellite is currently circling Venus and Mercury?
