Transcript of VENUS
The atmosphere on Venus is thick, rapidly spinning, that creates a hot planet with temperatures that are hot enough to melt lead. It also is filled with carbon dioxide and nitrogen gas. Venus's atmosphere is 96% carbon dioxide. The surface pressure is 90 times more than earth's surface because of the thickness and density. The similarities with Earth and the way the clouds reflect the sunlight, causes Venus to be the brightest. There are clouds that have a lot of acids(sulfuric acid). The clouds' layer is very thick which causes Venus not very visible. There is only a tiny amount of water that is detected in the atmosphere of Venus. The planet is raging with heat because the thick atmosphere traps the sun's heat/sunlight. Which causes the surface to be over 470ºC.
Orbit & Rotation
The planet orbits rotation period is 243 Earth days long. Venus rotates East to West. Seen from Venus, the sun would rise in the West and set in the East. As Venus moves forward in its solar orbit it moves backward on its axis, the cloud-level atmosphere zips around the planet in the opposite direction from the rotation every four days, driven by constant hurricane-force winds. About 90% of the surface of Venus appears to be recently solidified. Venus completes the orbit every 224.65 days.When Venus lies between the Earth and the Sun, a position known as inferior conjunction, it makes the closest approach to Earth of any planet at an average distance of 41 million km.
Venus is also called the evening star or the morning star in many cultures. It is also called Aphrodite. Venus is the second closest planet to the sun. It is the brightest planet in the night sky after the moon. It is also called the sister planet of Earth. That is because they share similar in size, mass, density, composition, and distance from the sun. Venus is the hottest planet in the solar system. It has no carbon cycle. Which is the way carbon dioxide is stored and replaced, on earth. On Venus, Venus's 1 day is equal to 117 Earth days. You can also see Venus sometimes passing by the face of the Sun.
ALL ABOUT VENUS
A word from The newspaper!
The heat in the atmosphere of Venus, induced from a strong greenhouse warming, might actually have a cooling effect on the planet’s interior. This counter-intuitive theory is based on calculations from a new model presented at the European Planetary Science Congress (EPSC) in Rome on Tuesday 21st September.
“For some decades we’ve known that the large amount of greenhouse gases in the atmosphere of Venus cause the extreme heat we observe presently,” explains Lena Noack from the German Aerospace Center (DLR) in Berlin, lead author of the study.
“The carbon dioxide and other greenhouse gases that are responsible for the high temperatures were blown into the atmosphere by thousands of volcanoes in the past. The permanent heat -- today we measure almost 470 degrees Celsius globally on Venus -- might even have been much higher in the past and, in a runaway cycle, led to even more volcanism. But at a certain point this process turned on its head -- the high temperatures caused a partial mobilization of the Venusian crust, leading to an efficient cooling of the mantle, and the volcanism strongly decreased. This resulted in lower surface temperatures, rather comparable to today’s temperature on Venus, and the mobilization of the surface stopped.”

Venus is made of rocks. the greenhouse effect is very effective on Venus(the greenhouse effect is when co2 on the atmosphere is like a blanket, that traps heat). The surface of Venus is 80% smooth. 2 areas that are higher( called continents)make the north and the south of Venus. There the north is called Ishtar Terra which is the size of Australia . The south part of the planet is called the Aphrodite Terra which is the size of South America. This Terra extends for almost 6 000 miles. On Venus there are more than a 1 000 volcanoes greater than 2 miles in diameter. From distance, on Venus it look like dots. There is a mountain on Venus called Maxwell Montes, which is claimed to be the highest mountain on Venus. There is also a mountain on the Ishtar Terra, at the eastern edge, that is about the size of Mount Everest. Venus has an iron core that is 3 000 km in radius. This planet does have a magnetic field because even if the Venus iron core has similarities with Earth's, Venus still doesn't rotate as fast to generate the same type of magnetic field that is on Earth.
That was it folks!
