Period 2

2. Sister planet Astronomers refer to Venus as Earth's sister planet
Both are similar in size, mass, density and volume
formed about the same time and condensed out of the same nebula
YET….

3. continued Venus is very different from the Earth has no oceans
surrounded by a heavy atmosphere composed mainly of carbon dioxide with virtually no water vapor
clouds are composed of sulfuric acid droplets
At the surface, the atmospheric pressure is 92 times that of the Earth's at sea-level

4. Temperature
Venus is scorched with a surface temperature of about 482° C (900° F)
It is the hottest planet in our solar system
high temperature is primarily due to a runaway greenhouse effect caused by the heavy atmosphere of carbon dioxide

5. Continued
Sunlight passes through the atmosphere to heat the surface of the planet
Heat is radiated out, but is trapped by the dense atmosphere and not allowed to escape into space
Scientists believe Venus was largely formed by volcanic processes

6. Orbit cycle
A Venusian day is 243 Earth days and is longer than its year of 225 day
rotates from east to west
To an observer on Venus, the Sun would rise in the west and set in the east
Because Venus is only slightly tilted on its axis, it has no seasonal variation

7. From earth….
inferior planet, it shows phases when viewed with a telescope from the perspective of Earth.
Brightest planet from earth
Galileo's observation of this phenomenon was important evidence in favor of Copernicus's heliocentric theory of the solar system

8. Atmosphere
There are strong (350 kph) winds at the cloud tops but winds at the surface are very slow, no more than a few kilometers per hour.
Clouds are so dense than you can never see the earth or the sun from the planets surface
There are no craters on the surface smaller than 1.25 miles

9. continued
Atmosphere is so dense the smaller asteroids are crushed before reaching the surface
No detectable magnetic field
No orbiting moons around
