•Question 2   (1 point)If a star has a parallax of 0.1 seconds of arc, then its distance is
 
a.2 parsecs b.5 parsecs c.10 parsecs d. 20 parsecs e.100 parsecs 
• Question 3   (1 point)In Star Wars, Han Solo claims the Millenium Falcon can make the Kessel Run in less than 12 parsecs. Huh? That's a distance, not a time! Star Wars fans claim this line doesn't refer to a trip in the conventional way, but rather a specific smuggling task through warped space. You should now know where the term parsec comes from. What is the parallax of a star 12 parsecs from Earth?
 
a. 12 arcseconds.   b. 6 arcseconds.   c. 1/6 arcseconds.  
•d. 1/12 arcseconds.   e. I don't know what parallax means!
