Venus
Considered Earth's "sister planet", Venus is the second planet from the Sun. Named after the Roman goddess of love, Venus' most prominent feature is it's thick atmosphere. Which is 92 times thicker than Earth's! Venus is one of the 4 terrestial planets.
♀ is the symbol for Venus. The symbol resembles a hand mirror or a distaff (a tool used in spinning thread)

Topic Specific Questions
Why might we expect Venus and Earth to be similar?
Venus and Earth are very similar in size and distance from the sun. However the similarities kinda stop there.
Explain what effect the atmosphere had on Venus’ current conditions.
The Venusian atmosphere is very dense and produces an intense greenhouse effect which heats up the planet. Russian space probes have been sent to Venus and survived for about an hour before melting due to the heat.

Discuss how volcanoes on Venus explain its lack of plate tectonics.
The planet's surface is largely resurfaced by volcanic eruptions. The mantle is constantly remade so it is unable to form into multiple plates.
Explain any theories that can explain why Venus rotates backwards.
Some believe that due to Venus’ thick atmosphere, the planet’s rotation was slowed down and eventually reversed. Others believe that Venus was hit by a celestial body and caused it to flip over.

FAQ
Could we inhabit Venus one day?
Venus’s environment is way too extreme for humans to settle. Its surface is the hottest in the Solar System. The thick atmosphere traps in heat with a greenhouse effect. The pressure is also brutal, its atmosphereic pressure is 92 times that of Earth. The air is full of toxic carbon dioxide and sulfuric acid clouds, which would make breathing impossible and corrode most materials. Not to mention, the weather is insane, with hurricane force winds and acid rain that never reaches the ground. Living in a floating city high in the clouds is the only semi-reasonable idea, but even that’s a stretch.
What's the magnetic field like on Venus?
Puny, Venus' magnetic field is 25,000 times weaker than Earth's.
