About Venus

• It is the second planet from the Sun and the sixth largest planet. 
• It is the hottest planet in the Solar System, even though Mercury is twice as close to the Sun and receives four times more solar energy.
• Venus’ atmosphere traps heat from the sun as an extreme version of the greenhouse effect that warms Earth. 
• Temperatures on Venus reach 880 degrees Fahrenheit (471 degrees Celsius), which is more than hot enough to melt lead. 
• Venus and Earth are often called twins because they are similar in size, mass, density, composition, and gravity. 
• Venus is only a little bit smaller than Earth, with amass of about 80% of Earth’s. 
• Composition:
• It is not a gas planet, but a rocky planet. The interior of Venus is made up of a central iron core and a rocky mantle, similar in composition to Earth.
• Its atmosphere is made up of mainly carbon dioxide (96%) and nitrogen (3.5%), with trace amounts of carbon monoxide, sulfur dioxide, water vapour, argon, and helium making up the other 0.5%.
