some stars are so far away that their position appear fixed as earth orbits the sun. other stars, however, appear over time to shift their positions relative to the background of "fixed" stars. suppose that the star shown below appears to shift through an arc of theta = 0 degrees 0 minutes and 1.5 seconds when viewed on the first day of winter and the first day of summer. if the distance from earth to the sun is about 1.5 x 10^8km, find the approximate distance from earth to the star
