WebAs long as that is true, the basic technique works. Now, the distance from the earth to the sun varies from about .98 AU to 1.02 AU, so using 1 AU is at least 98% accurate for the length of the adjacent side. Since it is just a multiplicative factor, this translates to at least 98% accuracy for the final answer, regardless of distance.

WebFigure 19.6 shows how such measurements work. Seen from opposite sides of Earth’s orbit, a nearby star shifts position when compared to a pattern of more distant stars. Astronomers actually define parallax to be one-half the angle that a star shifts when seen from opposite sides of Earth’s orbit (the angle labeled P in Figure 19.6).The reason for this definition is … Web2 dagen geleden · The Sun is 93 million miles away, so sunlight takes 8 and 1/3 minutes to get to us. ...
