Web( ③ ) The color of stars is related to their temperature, and since people cannot as yet travel the great distances to the stars and measure their temperature in a more precise way, astronomers rely on their color. ( ④ ) The interior of the star is at a much higher temperature, though it is concealed. WebOct 5, 2024 · The distance from earth to a star is determined using the stellar parallax equation distance = 1 / stellar parallax. Since 1989, Hipparcos has been measuring star parallax with a satellite that has been in space for over a decade.

WebSIM will measure the positions of thousands of stars extremely accurately — scientists call this process astrometry. SIM will create a “virtual grid” of reference points on the sky through measuring the separation between stars. By studying how the positions change with time, we will be able to measure distances from Earth to the stars. SIM
