Web3 mrt. 2024 · To measure the distance d of a faraway planet or near star S 1 by the parallax method, we observe it from two different positions (observatories) A and B on the Earth, separated by distance b at the same time as shown in Fig. Some distant star S is taken as reference. WebExpert Answer. 11. Astronomers often measure distances in parsecs. This term comes from the phrase "parallax arcsecond" because one parsec is defined to be the distance to a star whose parallax angle is one arcsecond. If we have a star whose parallax angle is 1/2 of an arcsecond, its distance is 2 parsecs. If the star has a parallax angle of 3 ... ear buds ear painWebParallax is measured based on the angle changing as the satellite orbits.
