Measuring Distances: On the Earth, in the Solar System, to the Nearby Stars

Part of the Astronomers’ Universe Series book series (ASTRONOM)


Distances play much the same role in astronomy and cosmology as perspective does in landscape painting: change either of them and the resulting picture changes. Accurate distances are required if you are to obtain a reliable picture of the Universe, just as they are in determining the size of the earth or the solar system or the Galaxy. The problem in each of these instances is the same: how is the requisite distance to be obtained when a direct measurement cannot be made? The solution is through the use of indirect methods, and I begin the description of them in this Chapter.
