venus_2.jpgVenus is like earths twin because they arevenus_planet.jpg similar in size.venus_planet.jpg You would be almost the exact same weight here as on earth. Venus is 12,107 kilometers in diameter. It orbits the sun in 224,701 earth days. Its rotation is 243.16 hours. Venus’s mass is 81% of earths. Its volume is 86% of earth’s volume. Venus is 107 million kilometers away from the sun. Its average temperature is 850 degrees F.
Venus is the second closest planet to the sun. Its atmosphere is made up of carbon dioxide and nitrogen. The atmosphere here is much thicker than earth’s atmosphere. Thick clouds surrounding Venus make a greenhouse effect that would be ten times as worse than regular green houses on earth. This makes it very hard for heat to escape the planet causing it to be very hot. Venus’s lack of ozone causes the heat to reach the surface directly. The clouds are composed of sulfuric acid, chlorine, and fluorine causing acid rain. So if you wanted to go out and play in rain one day you would melt, along with your house, and anything else on Venus if it was possible.
Venus was named after the Roman goddess of love and beauty. Sapus mons is a large volcano on Venus. Maxwell montes are the highest mountains on Venus. Ishtor terra is home to Venus’s four main mountain ranges. Aphrodite terra is a highland area.
Galileo was the first to study Venus in 1610. He saw that it had phases like our moon. Venus is so bright so they don’t know exactly who discovered it but they know that Galileo named it.
There are no moons that orbit Venus. Venus’s atmosphere is composed of carbon dioxide and its pressure is ninety times greater than earth’s. Probes really have not had much success on Venus because the clouds create an acid rain that melts all of it away. Many probes have tried to land on Venus but most of them failed. The first one to land on Venus was Venera 3, which was quickly melted away and no information came back. The most successful probe was a Russian probe named Venera 5 which was launched January 5th of 1969 and landed May 16th o 1969. With this scientist received 53 minutes worth of information on Venus.
