From Page 2:
1) The parallax angles (p) were:
Star A_________ arcsec, Star B_________ arcsec, Star C_________ arcsec.
2) Sketch on the "orbits" below an Earth-Sun-Star triangle for each of the three stars (like the “view from above” on p.1). You will have to vary the distance between the Sun and star to make the parallax angle larger or smaller, as appropriate to the Telescope Views on the web page.
3) Which star is closest to the Sun: A, B, or C? Which is farthest from the Sun: A, B, or C?
4) Imagine we had a star with a very large distance from the Sun. How large do you expect the parallax angle to be for this star?
5) Make a general statement about the relationship between the sizes of p and d. Can you express this as an equation?
From Page 3:
6) Compute the distance to each star from the parallax angles you measured in Question 1:
Star A_________ pc, Star B_________ pc, Star C_________ pc.
7) Convert these distances from units of parsecs (pc) to light years (ly):
Star A_________ ly, Star B_________ ly, Star C_________ ly.
