The Parallax Technique – National Radio Astronomy Observatory

WebThe parallax technique determines distance by measuring the angle of apparent shift in an object’s position, as seen from opposite sides of Earth’s orbit around the Sun. Using this method, astronomers were able to directly measure the distance to a region on the far side of our Milky Way Galaxy, past the Galaxy’s center. http://hyperphysics.phy-astr.gsu.edu/hbase/Astro/para.html WebThe really important thing is that the angle between the opposite side (the line from the sun to the star) and the adjacent side (the line from the sun to the earth) is 90 degrees. As long as that is true, the basic technique works. philadelphia usps network distribution center
