Astronomers use some smart methods to measure stellar distances. These distances are really too huge to be determined using traditional methods as they are beyond the scale of any physical instrument we use. WebTo measure distance in this manner, you take two images of a star field, one on each side of the Earth's orbit so you effectively have a baseline of 300 million kilometers. The closer stars will shift relative to the more distant background stars and by measuring the size of the shift, you can determine the distance to the stars. csl westmoreland dallas tx
