2. VENUS

3. Contents: Introduction Comparison with Earth Revolution (Year) Rotation (Day) Brightness Hotness Atmosphere Pressure Sulfuric acid rain Surface Exploration

4. It is the brightest object in the sky apart from the Sun and moon. It is also called “The Morning” or “ The Evening Star "

5. Venus is named after the Roman goddess of love and beauty.

6. Position in Solar system

7. To complete one orbit (revolution) around the Sun is called Planet Year.

8. Venus rotates in the opposite direction to the Earth’s rotation and very slowly.

9. Knowing that Venus rotates in the opposite direction as our own planet, What can you determine about sunrises and sunsets on Venus?

10. In fact, Venus has more volcanoes than any other planet in the solar system.

11. Venus is the hottest world in the solar system. In some places, it can be as hot as 1,000 F.

12. Venus’s dense atmosphere is mostly carbon dioxide that traps heat in a runaway version of the greenhouse effect. As a result, the average temperature on the Venus reach 870 F

13. The atmosphere on Venus is made of 96.5% carbon dioxide, 3.5% nitrogen, with minor amounts of sulfur dioxide, argon, water, carbon monoxide, helium and neon.

14. High-Density Atmosphere: The atmosphere on Venus is heavier than that of any other planet, leading to a surface pressure 90 times that of Earth.

15. Sulfuric Acid Rain: There is an evidence of lightning on Venus. It is not from water clouds, like it is on Earth. However, it comes from clouds of sulfuric acid .

16. Exploration(Venera 01-16): The Soviet Union (Russia) launched a total of 16 probes to Venus starting in 1961 and ending in 1983. This Photo by Unknown Author is licensed under CC BY-SA
