Trivia Questions

  1. What giant planet will rise this month in the constellation Libra?

    Taken with SkyNet by Dennis Hands
  2. Which planet is named after the Roman equivalent of the Greek god named “Zeus”?
  3. Name the comet whose fragments plunged into the atmosphere of Jupiter in July 1994.
  4. How long does it take for Jupiter to rotate once on its axis?
  5. What does this phrase describe: “I Eat Good Chocolate”?
  6. Jupiter contains how many Earth masses?

Correct Answers……..Winners:

  1. Jupiter…..… @JamesOn215: Jupiter moved into the constellation Libra last November and will travel thru it until this November. Into which zodiac constellation will it move next?
  2. Jupiter…….. @tiki: For the Greeks, Zeus was the lord of the sky and rain: meteorology! The rain of solar system debris that hits the Earth is certainly diminished by our big, big brother, the King of the planets. How much solar system debris does the Earth collect?

      It took 20 tries for one of my periscope guests to finally type the correct answer to this rather simple trivia question. Venus was tried four times and someone even tried the answer “the Sun.”

I wonder if the fact that the answer to the first question was also “Jupiter” had anything to do with it?

Table 1: Number of guesses to this question until the correct answer.
































  1. Levy…………….……………………@ed_132

Shoemaker Levy………..……@rossm3838

Shoemaker Levy 9…..…..….. @Kuubre85: Gene Shoemaker determined the origin of Meteor Crater in Arizona. What caused that crater outside of Winslow?

  1.     9.94 hours…………….@rossm3838: That’s a little more than 9 hours 55 minutes. Which planet has the shortest rotational period?


  1. The order of the largest moons of Jupiter in order of distance.……….. @Jacob48642: This is a nice little memory device to help students remember the Galilean moons.


I’ve heard that the two rules for a very good memory device is 1) to make it yourself, and 2) make it just a bit naughty.

So I made up this one:

“Research Indicate Retreating Vandals Underestimated Xena’s Gabrielle”?

What could it mean?

  1. 318 Earth masses………….@JamesOn215: Actually 317.83 Earth masses. As for size, more than a million Earth’s could fit inside the Sun. How many Moons would fit inside the Earth?

Don’t make light of this memory device.
