Use this interactive simulation of stellar parallax. Change the distance to the star to values given in column 2. Write down the parallax angle in arcsec for each distance. Convert the parallax angle to radians. Calculate the distance. If your calculation is correct, your number in the last column should be similar to the number in column 2 (NOT THE SAME!). 1 AU is 4,85 x 10-6 pc (Don't write units with your answer!) Measured (true) Distance from "Sun" in pc Parallax angle n (in radians) (use 2 significant D (round your answer to 2 figures) Calculated distance Object Position Parallax angle (in arcsec) decimal places) Nearest 0.5 Intermediate 1 Farthest 1.5
