    system planets” (p. 24), how many DO NOT orbit the giant planets?

 

  1. (The answer must have two different numbers to fill in the blanks.) The orbital resonance of Io, Europa and Ganymede is “1 : ________  : ________” (p. 24)

  1. (The answer must be two words of direction, like north or east.) At UT 13:40 Tuesday, July 24, 2018, the moon Ganymede will transit the face of Jupiter.   Satellites move across the face of the Jupiter from __________ to _____________. (p. 235)

  1. What’s the total number of moons of Jupiter we have discovered (to date)?

OK, pencils down. Let’s trade with a neighbor and check one another. Here are the correct answers and your “neighbor” who got the correct answer on my Periscope broadcast on July 23, from 8:00 am (eastern US) to 9:00.

Correct Answers……..Periscope Winners:

  1. Galileo……… . @Tatoolover26: Galileo used a simple “spyglass” he reproduced from written directions. Spyglasses were being used as a military tool, allowing armies to see the enemy at great distance. Galileo pointed his telescope upward. But Galileo wasn’t the first to examine the Moon with this new “telescope.”

  1. Ganymede…….. @EagleSoarsUSA:  What keeps Ganymede from being a “planet”?   It’s the first part of the IAU’s definition for the word “planet”. 1) If it orbits a planet, it’s a moon.

  1. three….…… …@Steelman_MJW: The three other natural satellites are our Moon, Phobos and Deimos. This year is a great opportunity to see the two moons of Mars. Aim your best telescope that way.

  1. 1 : 2 : 4………… ….@EagleSoarsUSA: For every one orbit by the moon Io, Europa will orbit Jupiter two times and Ganymede will orbit 4 times.  Is there an orbital resonance in the planetary orbits of our solar system?

  1. East to West… ……..@speear40:  When the moon is moving behind Jupiter it appears to move from west to east.  Have you ever seen a transit?

The transit of Venus in 2004  Barbara and I went to South Africa to view this rare transit.  Also, East to West!!

 

  1. 79 moons of Jupiter………… ….Steelman_MJW: Can you name them?
