Venus (Aya)
= = Venus is referred as earth’s twin planet since it has almost the same size, mass, gravity, and overall composition > > >> - Neon >> - Helium >> - Carbon monoxide >> - Water vapor >> - Argon >> - Carbon dioxide >> - Nitrogen
 * =**Orbital Period:**=
 * Orbits with an average distance of about 108 million kilometers in 224.65 days
 * =**Date of discovery:**=
 * Date of Discovery is prehistory because Venus was visible since the Earth was formed.
 * =**Scientific History:**=
 * Although people knew Venus was there since it is visible, scientists had not sent the spacecraft to the planet. However, in 1961, the first spacecraft Sputnik 7 was sent to the Venus. In 1962, the Marina 2 was sent and was followed by the Russian Venera 7 in 1970. Venera 7 could only stay there for 23 minutes because of the high temperature. It is being burnt. After sending many spacecraft, Magellan could finally success in revealing craters and Volcanoes existed in 1990. Recently, Venus has been studied by the European Space Agency's Venus Express spacecraft.
 * =**Mythology:**=
 * The planet Venus is also known as the goddess of Beauty and Love.
 * It is named after Aphrodite.
 * Aphrodite represents hte inncent manner, pure feathers and was seen smiling.
 * To the Romans she was known as Venus. The child was the goddess Harmony.
 * When the scientists first discovered the planet, they saw beautiful swirls of clouds, and thought they hid the beauty
 * =**Size:**=
 * Venus has a diameter that is about 95% of Earth’s. It is 12,100 km across.
 * A volume of 9.38×1011 km3
 * A mass of 4.868 x 1024 kg
 * Venus has an average temperature that is 410°C higher than the hottest deserts on Earth.
 * =**Composition:**=
 * - Sulfur dioxide
 * The composition of Venus is similar to Earth, with a core of metal, a mantle of liquid rock, and an outer crust of solid rock
 * At the center of Venus is a solid or liquid core of iron or nickel
 * The planet doesn’t have a large difference in temperature between the inner and outer core
 * =**Atmospheric conditions:**=
 * Thick, pale yellow clouds in atmosphere make its surface impossible to see from Earth.
 * Thick atmosphere is made up of carbon dioxide
 * Have some similarities to Earth.... landscape dominated by volcanic features, faulting, and impact craters
 * Greenhouse effect: the cloud cover traps the heat of sun, therefore its temperature is high
 * =**Resources:**=
 * Mountain that forms landscape and it consists of //__metal__// and natural resources of //__plant__//
 * Made of //__Carbon Dioxide__// mainly
 * 85% of Venus is covered by //__volcanic rock__//
 * //__Sulfur dioxide, neon, helium, carbon monoxide, water vapor, argon, nitrogen__//


 * =**Significant & Noteworthy features:**=
 * Although it is called Earth’s twin planet, it does not have water
 * It does not have water, but it has water vapor. Therefore, there are rain clouds. It is unlike rainclouds we are seeing, but these are Sulphuric Acid clouds which produce Sulphuric Acid rain.
 * Venus is also known as a lifeless world, but some scientists claim that there might be living microbes.
 * Some research shows that the Venus used to be a warm planet with water. It was similar to the Earth
 * =**What we don't know? :**=
 * Venus is a brightest planet in the solar system. People are able to see it before sun rises or after sunset. Therefore Venus is also called “morning star” and “evening star”
 * =**Future plans or expeditions:**=
 * Even though Venus Express succeeds to land on Venus, but it does not solve all the questions about Venus. Scientists need to build another spacecraft to solve the questions on Venus’s atmosphere. Future plans for scientists are to solve these questions “ Why does Venus have a strong greenhouse, and Earth and Mars do not? ”, “ Why did Venus and Mars evolve to a stagnant lid regime, unlike Earth? ”
