Take a Trip Through The Solar System! Quiz


You will be escorted through the solar system, and learn little bits of information on the way. In order to get back home to Earth though, you must answer one question about each planet. Good luck!

Question 1 of 10
1. Stars are given letters which designate the temperature. The sun is classed as a yellow star, so is in which category? Hint


Question 2 of 10
2. Next we come to Mercury, the first planet from the sun, and the only planet other than Venus with no satellites.

Compared to Earth, how long is one day on Mercury?
Hint


Question 3 of 10
3. Next stop: Venus! Venus is the brightest planet in our solar system. Why is Venus so bright?
Hint


Question 4 of 10
4. Planet Earth, the planet in our Solar System that can support life. But the dirt and hard surface that we walk on is very different from the core of the Earth. What is the core of the Earth made of? Hint


Question 5 of 10
5. Now we come to Mars, otherwise known as the Red Planet because its surface is covered with a thin layer of iron oxide.

Which of these describes Mars's satellites, Phobos and Deimos?
Hint


Question 6 of 10
6. We have now come into orbit of Jupiter. We can't actually land on Jupiter though, because it is a gas planet, not a solid one.

How long are Jupiter's seasons?
Hint


Question 7 of 10
7. We have now arrived at Saturn, the ringed beauty. Did you know Saturn's rings are not solid, but they are chunks of gas, dust and ice ranging from the size of sand to 1/2 a kilometer long?

What day of the week has a name derived from Saturn?
Hint


Question 8 of 10
8. Now we are at Uranus, the planet that is tilted on its side! People believe something huge crashed into Uranus a long time ago, throwing it off its regular rotational axis.

What colour does Uranus appear from Earth?
Hint


Question 9 of 10
9. We're nearly there - just one more planet! Neptune is very similar to Uranus - Uranus is just slightly bigger than Neptune.

What is Neptune's mantle made of?
Hint


Question 10 of 10
10. We are at our last destination, the dwarf planet Pluto. The surface of Pluto is thought to be very icy. Pluto is a frigid cold place, and has at least four frigid cold moons.

What are the names of the first three to be discovered?
Hint

Quiz Answer Key and Fun Facts
1. Stars are given letters which designate the temperature. The sun is classed as a yellow star, so is in which category?

Answer: G

The sun is only a medium temperature. Most people connect red with hot and blue with cold, but with stars the blue ones are very, very hot and are designated as class O or B. The red ones are slightly cooler (although still very hot!) and fall in the classification K and M. Our sun is a yellowish sort of colour, cooler than other stars and is classed as a G2 star, with the two meaning it is one of the hottest in the G category; only G1 is hotter..
2. Next we come to Mercury, the first planet from the sun, and the only planet other than Venus with no satellites. Compared to Earth, how long is one day on Mercury?

Answer: Nearly two Earth months long

One day on Mercury is about 59 Earth days, to be precise. A day on Mercury may be long, but one year is not at all! One year on Mercury is about 88 Earth days - you wouldn't even be able to fit two Earth days into one year on Mercury! Mercury is the closest planet to the sun, about 58,000,000 km from the sun so the highest temperature Mercury will get to is 430 degrees Celsius - too hot for anyone to live there.
3. Next stop: Venus! Venus is the brightest planet in our solar system. Why is Venus so bright?

Answer: Its thick clouds reflect sunlight

Venus is one of the brightest objects in the night sky, after the moon. The atmosphere of Venus is made of 97% carbon dioxide, and the thick swirling clouds are partly made of sulphuric acid. If you ever get a chance to go to Venus, don't even try to breathe.

It won't work. But as soon as you landed on the surface of Venus, you wouldn't live for very long because the carbon dioxide on Venus would form the greenhouse effect, trapping a lot of heat inside the atmosphere. The temperature on Venus can be nearly 470 degrees Celsius!
4. Planet Earth, the planet in our Solar System that can support life. But the dirt and hard surface that we walk on is very different from the core of the Earth. What is the core of the Earth made of?

Answer: Molten nickel and iron, and some other elements

The core of the Earth is very hot- an estimated 3677 degrees Celsius! Some people think, though, that the core of the Earth is cooling about 100 degrees Celsius every billion years.
5. Now we come to Mars, otherwise known as the Red Planet because its surface is covered with a thin layer of iron oxide. Which of these describes Mars's satellites, Phobos and Deimos?

Answer: They are irregularly shaped

The names Phobos and Deimos come from the Greek language, Phobos meaning fear and Deimos meaning panic, or terror. Phobos and Deimos are thought to have once been asteroids, but the Martian gravitational field pulled them into Mars' orbit. Both satellites have many craters, quite the opposite of having no craters whatsoever.
6. We have now come into orbit of Jupiter. We can't actually land on Jupiter though, because it is a gas planet, not a solid one. How long are Jupiter's seasons?

Answer: Roughly three Earth years

Jupiter doesn't have Earth-like seasons because it is tilted only three degrees on its axis. Seasons are primarily caused by the tilt of a planet, and there needs to be a major tilt in order for seasons to occur. Consequently, there is little difference between the seasons on Jupiter.

This is because it is winter when one hemisphere is tilted away from the sun, and summer when the other hemisphere is leaning towards the sun. Jupiter does have some minimal seasonal differences due to the eccentricity of its orbit, but they are not like Earth's - the seasonal heating and cooling affects the entire planet in the same way, not heating one hemisphere and cooling the other.
7. We have now arrived at Saturn, the ringed beauty. Did you know Saturn's rings are not solid, but they are chunks of gas, dust and ice ranging from the size of sand to 1/2 a kilometer long? What day of the week has a name derived from Saturn?

Answer: Saturday

This is also linked with French, too. Here is what each celestial object translates to as a day of the week:
Monday = The Moon
Tuesday = Mars
Wednesday = Mercury
Thursday = Jupiter
Friday = Venus
Saturday = obviously, Saturn
Sunday = The Sun

These make more sense if you do it in French. Find a French-English dictionary and look it up!
8. Now we are at Uranus, the planet that is tilted on its side! People believe something huge crashed into Uranus a long time ago, throwing it off its regular rotational axis. What colour does Uranus appear from Earth?

Answer: Blue-green

Uranus is mainly composed of hydrogen - 83% hydrogen, 15% helium and 2% methane. Uranus is a blue-green colour because the methane in the upper layer of the atmosphere absorbs red light.
9. We're nearly there - just one more planet! Neptune is very similar to Uranus - Uranus is just slightly bigger than Neptune. What is Neptune's mantle made of?

Answer: Water, ammonia, methane ices

Neptune has the strongest winds in the solar system - wind speeds that have been discovered are around 2253 km/h!
10. We are at our last destination, the dwarf planet Pluto. The surface of Pluto is thought to be very icy. Pluto is a frigid cold place, and has at least four frigid cold moons. What are the names of the first three to be discovered?

Answer: Charon, Hydra, Nix

Charon was discovered in 1978 and Nix and Hydra were discovered in 2005 by the Hubble Space Telescope.

Pluto was once a real planet, but in 2006 was classified as a dwarf planet because:

1. Pluto crosses into Neptune's orbit, a real planet must have cleared its own way in its own orbit.
2. Pluto is thought to have formed somewhere else in outer space, beyond our solar system and got pulled in by the Sun's gravity. It was also thought to have once been one of Neptune's moons that escaped from Neptune's gravitational pull.
