Correct option is A
Venus is called Earth’s twin because it is similar in size, mass, and composition to Earth. Both planets have a rocky surface and a thick atmosphere, but Venus has a surface temperature exceeding 460°C, making it the hottest planet in the solar system.
Information Booster:
- Atmosphere: Mostly carbon dioxide with clouds of sulfuric acid.
- Rotation: Venus rotates in the opposite direction to most planets (retrograde rotation).
- Surface Pressure: 90 times that of Earth's atmosphere.
- Day Length: A day on Venus (243 Earth days) is longer than its year (225 Earth days).
- Exploration: NASA's Magellan spacecraft mapped its surface in the 1990s.
- Brightness: Venus is the brightest object in the night sky after the Moon.
Additional Knowledge:
- Mars (b): Known as the "Red Planet," famous for its iron oxide-rich surface.
- Sun (c): A star, not a planet, at the center of our solar system.
- Jupiter (d): Largest planet with the most moons, known for its Great Red Spot.
Key Points:
- Venus's extreme greenhouse effect causes its high surface temperatures.
- Its dense atmosphere reflects sunlight, making it highly visible.
