...from the pole of the ecliptic to the ecliptic itself. The length of the major axis simply expresses **the ratio of the velocity of light to the velocity of the earth in its** path and is therefore constant. It has been found by careful observation of the stars that this major... | |

...any such aberrational ellipse is always parallel to AC. j'.r the ecliptic, and since it is equal to **the ratio of the velocity of light to the velocity of the earth,** it is necessarily constant. This constant length subtends an angle of about 40* at the earth;. the... | |
