Question 6 Betelgeuse, (typically pronounced \"beetle juice,\" but some people insist it should be \" bet el geese\") is the bright red star in the constellation Orion (top left in picture below). Its parallax is $7.60 \times 10^{-3}$ arcsec. Calculate the distance, in parsecs, of this star from the Earth. Show your steps. Question 7 In order to measure the large distances you found in the questions above, what baseline must astronomers be using? Question 8 Is the parallax for Betelgeuse larger or smaller than that of Proxima Centauri? What does that tell you about the general relationship between parallax and distance?
