What’s Up in Space?

(Wish you were here.)

Today we have five questions, so we will take five minutes to complete the quiz today.

With that in mind, ladies and gentlemen, please get out a clean sheet of paper and a No. 2 pencil and prepare for today’s Astronomy Pop Quiz.

DMG procedures and expectations apply; 1) if you find a mistake, please let me know, and b) do your best.

The topic today: Current Events Pot Pori

You have five minutes to complete the quiz. Begin now.

  1. What annual meteor shower is made from the debris left by comet Swift-Tuttle?

  1. Comet Swift-Tuttle has a 1:11 orbital resonance with one of the planets. A 1:11 orbital resonance means that for every one orbit the comet makes around the Sun, a particular planet orbits the Sun eleven times?  Which planet?


  1. Name the Band: On page 14 of the book Ripples in Spacetime by Govert Schilling, he writes that before Einstein, the idea of space was like a three dimensional graph paper. “And time? The imaginary clock of nature ticks away the moments that make up a dull day….” Can you name the Band?

  1. Name the space probe launched this past weekend that will touch the outer layers of the solar atmosphere.

  1. The Sun rose this morning about 90 minutes ago, and the Moon is still below my Eastern horizon. What is the phase of the Moon right now?

Play live on Let’s talk astronomy” 8 am, Mondays

Correct Answers……..Periscope Winners:

  1. Perseids………. @Pircano: Italian astronomer Giovanni Schiaparelli (1835-1910) discovered the resemblance of the orbit of the Perseids to the orbit of comet Swift-Tuttle. This was the first time a meteor shower was identified a specific comet. Swift-Tuttle has an orbital period of about 120 years.

  1. Jupiter…….. @ArisKris: Orbital resonances aren’t that unusual The orbital period of the Jovian moon Io is almost exactly half that of Europa. Orbital resonance also graces the asteroid belt, with the gaps at 1:3, 2:5, 3:7 and 1:2 ratio of Jupiter’s orbital period.

  1. Pink Floyd….………@TwiggerHorn: “Tired of lying in the sunshine staying home to watch the rain.,,,So you run and you run to catch up with the sun but it’s sinking, racing around to come up behind you again.   The sun is the same in a relative way but you’re older, Shorter of breath and one day closer to death.” Dark Side of the Moon

  1. Parker…………….@Camerojeff599: Here’s a video about the Parker mission

  1. Waxing crescent………..@rossm3838: We had a New Moon for the Perseids, giving the shower this year more potential. First Quarter happens about seven days later, then Full, then Third quarter, then New Moon again, each a little less than 7 days apart If New Moon was just Saturday, two days ago, not enough time has passed to get First quarter. In between, find waxing crescent.

Thanks goes out to all participants, and Congratulations to everyone who got one right.
