Quiz Answer Key and Fun Facts

1. Mercury is the planet closest to the sun, but why is Venus the hottest planet?

Answer: Venus has the greenhouse effect

Venus' greenhouse effect lets in radiant energy from the sun, but prevents it from escaping. Its thick atmosphere of, mostly, carbon dioxide traps heat. The temperature on Venus goes up to 860F. Hotter than most ovens and hot enough to melt lead.

2. Which of these is true about Jupiter?

Answer: It is 90% hydrogen and 10% helium

Jupiter is the largest planet in our solar system. Some scientists believe if there was any form of life on Jupiter, it would be at the bottom of the surface, where the temperature rises to around 70F. Many scientists doubt there is life on Jupiter.

3. Which of these has had its classification changed?

Answer: Pluto

Pluto was discovered in 1930 by Clyde W. Tombaugh. Pluto was downgraded from a planet to a dwarf planet.

4. What planet has seasons which are most like those of the Earth?

Answer: Mars

Mars' temperature varies just like the Earth. It can range from -150F to 70F. The axial tilt of Mars is very similar to that of Earth, so the seasons follow a similar pattern.

5. What planet is known as the Earth's twin?

Answer: Venus

Venus is slightly smaller and is the closest planet to Earth.

6. What is the farthest planet that can be seen without a telescope or binoculars?

Answer: Uranus

7. When did the spacecraft Ulysses reach Jupiter?

Answer: 1992

While on the journey, Ulysses gathered data that Jupiter's solar wind had a greater effect on its magnetosphere than previously suggested.

8. What probe was sent to Saturn in 1977?

Answer: Voyager 1&2

Voyager 1 reached its destination in 1980, Voyager 2 in 1981. Cassini is expected to reach Saturn in 2004.

9. What 20-year period did Pluto stay inside Neptune's orbit?

Answer: Jan 23, 1979-Feb 11, 1999

Pluto stays inside Neptune's orbit every 20 years before it rotates.

10. Earth is the fifth largest and the densest of the solar system.
