Questions and Answers
Why is Venus referred to as Earth's twin?
Why is Venus referred to as Earth's twin?
- It is similar in size and structure to Earth. (correct)
- It is the only other planet in our solar system known to potentially support life.
- It has the same axial tilt as Earth, leading to similar seasonal patterns.
- It has a similar atmospheric composition to Earth.
Although Mercury is closer to the sun, why is Venus hotter?
Although Mercury is closer to the sun, why is Venus hotter?
- Venus's core produces more internal heat than Mercury's core.
- Venus has a higher albedo, reflecting more sunlight and trapping more heat.
- Venus's slower rotation allows for more even heat distribution across the surface.
- Venus has a thicker atmosphere composed of greenhouse gases, which traps heat. (correct)
What is a unique characteristic of Venus's rotation compared to Earth and most other planets?
What is a unique characteristic of Venus's rotation compared to Earth and most other planets?
- Venus has no rotation; it is tidally locked with the Sun.
- Venus rotates in the opposite direction (retrograde) compared to Earth and most other planets. (correct)
- Venus's rotation is highly irregular, varying significantly over long periods.
- Venus rotates much faster than most planets, resulting in very short days.

Study Notes
- Venus is the second planet from the Sun.
- Venus is Earth’s closest planetary neighbor.
- Venus is a terrestrial planet, characterized as small and rocky.
- Venus is the hottest planet in the solar system, despite Mercury being closer to the sun.
- Venus has a thick atmosphere filled with greenhouse gas carbon dioxide and yellowish clouds of sulfuric acid.
- The atmosphere traps heat, making the surface feel like a furnace.
- The surface temperature on Venus reaches about 900 degrees Fahrenheit (475 degrees Celsius).
- The surface is rusty-colored, featuring intensely crunched mountains and thousands of large volcanoes.
- There is a possibility of active volcanoes on Venus.
- Venus has crushing air pressure at its surface, more than 90 times that of Earth.
- The air pressure is equivalent to the pressure a mile below the ocean on Earth.
- Venus is named after Aphrodite, the Roman Goddess of Love and Beauty.
- Venus appeared as the brightest planet in the sky in ancient times.
- Venus is called Earth’s twin due to similarities in size and structure.
- Venus spins in the opposite direction of Earth and most other planets.
- The sun rises in the west and sets in the east on Venus.
- Venus reflects 70% of the sunlight that reaches it.
- Venus is the brightest planet in the night sky.
- Venus has a very slow rotation, making its day longer than its year.
- It takes about 243 Earth days for Venus to spin around once.
- It takes 225 Earth days for Venus to orbit the sun.
Venus Exploration
- More than 40 spacecraft have launched for Venus.
- Japan's Akatsuki is currently in orbit around Venus.
- Akatsuki’s mission is to study weather patterns, confirm the presence of lightning in thick clouds, and search for signs of active volcanism.
- NASA's Mariner 2 was the first spacecraft to visit any planet beyond Earth.
- Exploring the surface of Venus is difficult because of the intense heat and crushing air pressure.
- The Soviet Union's Venera 13 probe survived on the surface for a little over two hours in 1981.
