Solar System Quiz

Quiz Image

WARNING: This is a solar system quiz for anyone who wants to try anything a bit more advanced. Some questions may be hard. I did my best to make sure my questions don't get outdated, but if some are, I apologize.

Good luck on this quiz. There is at least one question about every planet in the solar system, excluding Planet Nine because not much is known about Planet Nine at the time this quiz was made (Northern Hemisphere Autumn of 2016). There is also a question about asteroids, comets meteoroids and a question each about the dwarf planets Ceres, Pluto, Haumea, Makemake and Eris, unless some/all are now recognized as official planets. Good luck!

  1. Let's start with an easier question. Which of the objects below is the largest?
  2. Here's another easier one (don't worry, things will get more advanced later on). What are the colours of Pluto?
  3. Earth is 5.972 x 10^24 kg in mass. Approximately how many times more massive is the Sun?
  4. How hot is the surface of the Sun (in degrees Celsius)? Fahrenheit to Celsius: (?-32) x 5 í· 9
  5. TRUE OR FALSE Mercury has the most extreme temperature changes in the solar system
  6. Venus is the hottest planet in the solar system (average temp. 464 C, highest temp. 482 C). This is due to a gas trapping heat called...
  7. Mars has the longest canyon in the solar system. How long is it, in km? miles to km: ? í· 0.621371
  8. Ceres is a dwarf planet and an asteroid. Where is it?
  9. Jupiter's Great Red Spot has a lifespan of over 350 years, but isn't permanent (if your teacher or book says otherwise, they are WRONG). What evidence shows it will/might disappear?
  10. All the Jovian planets (Jupiter, Saturn, Uranus, Neptune) have rings, but Saturn's are the most visible. What are they made of?

  13. Pluto is 2374 km across. Which dwarf planet is larger in terms of diameter?
  14. Haumea has one of the fastest, if not the fastest, rotation periods in the solar system. How long is a rotation period on Haumea?
  15. Makemake is about 1430 km across. Which dwarf planet(s) is smaller?
  16. Eris was once thought to be larger than Pluto in terms of diameter, but ever since 2015, that has changed. What made scientists overestimate Eris's diameter? NOTE: Eris has more mass than Pluto, but is only 2326 km across
  17. What's the difference between an asteroid, meteoroid and comet?
  18. What is the DEFINITION of a planet?
  19. Almost there! This and the last question are easier! Earth is 12 756.274 km across the equator. Which is not larger than the Earth?
