Question 1

True or false: Venus is the hottest planet because it's closest to the Sun.

Accepted Answer

False. Mercury is closer, but Venus's thick carbon dioxide atmosphere creates a runaway greenhouse effect, making it hotter—up to 900°F.

Question 2

True or false: Venus is sometimes called Earth's twin because it has liquid water oceans.

Accepted Answer

False. Venus is called Earth's twin due to similar size and mass, but it has no liquid water—its surface is a scorching, dry desert.

Question 3

True or false: A day on Venus is longer than a year on Venus.

Accepted Answer

True. Venus rotates extremely slowly—one full rotation takes 243 Earth days, while its orbit around the Sun takes only 225 Earth days.

Question 4

True or false: Venus spins in the opposite direction of most other planets.

Accepted Answer

True. Venus rotates retrograde—from east to west—so the Sun rises in the west and sets in the east, unlike Earth and most planets.

Question 5

True or false: Venus has phases like the Moon when viewed from Earth through a telescope.

Accepted Answer

True. Because Venus orbits between Earth and the Sun, it shows crescent and gibbous phases, first observed by Galileo in 1610.

Question 6

True or false: Venus's clouds are made of water vapor, similar to Earth's.

Accepted Answer

False. Venus's clouds are composed of sulfuric acid droplets, not water—making them highly corrosive and reflective, giving Venus its bright appearance.

Question 7

True or false: The pressure at Venus's surface is about the same as being 3,000 feet underwater on Earth.

Accepted Answer

True. Venus's atmosphere is 90 times denser than Earth's, creating crushing surface pressure equivalent to nearly a mile deep in the ocean.

Question 8

True or false: Venus has no volcanoes because its surface is too old and stable.

Accepted Answer

False. Venus has more volcanoes than any other planet in our solar system—over 1,600 major ones, many possibly still active.
