appears to be on a “short leash” to the sun. Mars and Jupiter have a variation of 0 degrees to 180 degrees with the sun as a reference. 1 / 1 point Which other planet do you think has a “short leash” to the sun and like Venus is only viewed near the time of sunset or sunrise? 1) Mercury 2) Saturn Notice that Mars is found near the star Regulus (circled star in image below) of the constellation Leo. Remember when you observe at the same time the stars will drift towards the west (clockwise when you face south) each night. Outdoors we would have to measure this change as an angle. After installing the Angle/Measure plugin , record the angular separation between Mars and Regulus.

1) east to west 2) west to east Question 13 0 / 1 poin t Why? 1) because the celestial sphere generally moves in that direction with time 2) Mars independently moves among the stars in this direction Question 14 0 / 1 poin t What was the general (majority) direction Mars moved with respect to the stars during January through February? 1) east to west 2) west to east Question 15 1 / 1 poin t Why? 1) because the celestial sphere generally moves in that direction with time 2) Mars independently moves among the stars in this direction Normally a planet will move from west to east as seen against the starry background. Occasionally a planet may be observed to move east to west as seen against the background stars. This “backward” or abnormal motion is known as retrograde motion.
0 / 1 point Examine the above plotted motion of Mars and explain to the viewer how the planet can move in this way as seen by their own eyes. Try your best-no research attempt to explain this unusual behavior. All answers accepted . I want to say that it is because of the earths axis and tilt relative to the planet. Then I think about the other planet orbiting as well. We can't tell here on earth how far the planet is away from us but if you can imagine for a moment that it is orbiting around the sun it should be a line moving back and forth if you could look at it all the time. I can see this in my mind how it's going in a circle and if I am looking at a horizontal view of it's orbit it's going to move back and forth.

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.
