( SHOW WORK FOR CREDIT ) Suggestion-To solve this problem you need to know how far (degrees of angle) Saturn travels in a year. It is known that 5 degrees separates the "pointer stars" of the Big Dipper. On your computer screen measure the distance between these two stars. That distance on your screen now becomes a map scale. With such a scale- like one found on a highway map-you can now measure the angular distance that Saturn will move in a year.

This is easier to do with the plug in but any way I will use a tape measure. according to my screen 1/2" = 5 degrees measuring the pointer stars. The movement in one year is slightly over 1" using the plug in you get 12 degrees which makes sense. Therefore (360/12)1=30 years researching the answer I found it was 29.457. So my calculations are close. This question has not been graded. The correct answer is not displayed for Written Response type questions. : 12 degrees/year, 360 degrees/12 degrees/yr. The angle between the stars of the Dipper is like a map scale. This distance on the Saturn moves about two Dipper star lengths in a year. 0 / 3 points 21-23: Summarize at least three main points you learned about planetary behaviors as seen from your backyard . 1. the pointer stars of the big dipper are 5 degrees apart making it easy to scale any screen. 2. Planets wander around the night sky and are not parallel with the rotation of the stars. 3. I learned how to use Stellarium which is a great tool that I can use in my free time to identify stars in the night sky in my own backyard. 4. I learned that it is possible that a long time ago there may be some correlation between the 7 days of the week and the seven "Gods" of the ancient sky. This question has not been graded.

Use the following information to answer Question 3 Click here to view Ptolemaic Phases of Venus Simulation (will open in a new window) Background-In the geocentric (Ptolemaic-earth centered) view, the Sun and Venus move in the way displayed to accommodate the observations seen from our backyards as follows: a. Venus retrogrades-the planet is shown moving on the epicycle (orbital circle) b. Venus is always seen close to the sun-the angle of seperation is always small (it is on a "short leash" to the Sun) 1 / 1 point When Venus is closest to the earth the backyard observer would see: 1) a fully illuminated Venus 2) Venus in the eastern sky at sunset 3) Venus in the western sky at sunset 4) nothing-Venus would have its dark side towards earth Quest ion 2 0 / 1 poin t Information:

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
