Venus' complete orbit around the sun takes 225 earth days. Less than a year for us. Venus' temperature is about 864 degrees F The United States, Soviet Union, and European Space Agency have deployed more than 20 spacecraft's to Venus. Including Mariner 2, Venera 7, and Venera 9. Venera 9 returned the first photographs of the Venusian surface. The atmosphere of Venus is 96.5 carbon dioxide, 3.5 nitrogen, with minor amounts of sulfur dioxide, argon, water,carbon monoxide, helium and neon. Venus has many layers of clouds made of sulfuric acid. Venus is the hottest planet in the solar system. The surface of Venus is extremely dry. With no liquid water. Venus is mostly flat plains with thousands of volcanos. With lava that flows in long canals. • Even though Mercury is closer to the Sun Venus is Hottest because it is mostly made up of carbon dioxide, which is the primary green house gas. The solar heat enter but can't leave. Basically making Venus an oven. Venus has a similar gravitational pull to Earth. Earth's gravitational pull is 9.8 m/s squared, while Venus' is 8.87 m/s squared. Galileo Galilei was the first astronomer to discover Venus. Galileo discovered Venus in 1610 He found out that Venus goes through phases like the moon which helped support the theory where planets orbit the Sun Venus is known as the planet named after the goddess of love Aphrodite. Venus has been known throughout history as the brightest planet. Venus and Earth are often called twins because they are similar in size, gravity, mass, and density. • www.space.com/44-venus-second-planet-from-the-sun-brightest-planet-in-solar-system.html • By Charles Q.
