 2 Text,  8 |          be able to determine the distance of a certain number of stars,
 3 Text,  8 |           definite measure of the distance of any one star. As the
 4 Text,  9 |     others are nearly at the same distance. About 100 stars, all told,
 5 Text,  10|      shall take as our standard a distance 400,000 times that of the
 6 Text,  10|    measure out in any direction a distance twice as great as this then
 7 Text,  10|           this then another equal distance, making one three times
 8 Text,  10|           on, as the cube of each distance. Since each sphere includes
 9 Text,  10|           400,000 times the sun's distance. We are thus enabled to
10 Text,  11|          as our unit. We find the distance of the surface of this sphere
11 Text,  11|       would be contained within a distance found by multiplying 400,
12 Text,  11|     multiplying 400,000 times the distance of the sun by 500; that
13 Text,  11|          is 200,000,000 times the distance of the sun. This is a distance
14 Text,  11|    distance of the sun. This is a distance through which light would
15 Text,  12|          as far, carrying it to a distance which light would require
16 Text,  14|          radius 800,000 times the distance of the sun, and therefore
17 Text,  14|     diameter 1,600,000 times this distance, would, judging by the proper
18 Text,  15|         of estimating the average distance of certain classes of stars.~
19 Text,  16|        the earth, determine their distance. But since every star has
20 Text,  16|           to estimate the average distance by this method. When an
21 Text,  16|          any determination of the distance of the stars based on our
22 Text,  16|       Milky Way are situated at a distance between 100,000,000 and
23 Text,  16|         and 200,000,000 times the distance of the sun. At distances
24 Text,  16|        than 200,000,000 times the distance of the sun.~
25 Text,  19|         can penetrate. Up to this distance we see the stars just as
26 Text,  19| invisibility is due only to their distance and the faintness of their
