...refraction of any kind. All these causes being rejected, it occurred to him that the appearances might arise from the progressive motion of light combined with the motion of the earth in its orbit. He reasoned somewhat in this manner. If the earth were at rest, it is plain that a telescope, to admit... | |

...minute. 888. The phenomenon, called the aberration of the fixed stars, arises from the motion of the rays of light, combined with the motion of the earth in its orbit. For if the velocity of the earth have any determinate ratio to the velocity of light, it will be evident... | |

...the aberration or difference between the true and apparent place of a fixed star, is occasioned by the progressive motion of light, combined with the motion of the earth in its orbit ; and that this aberration when greatest amounted to 20 '232. Now the earth describes an arc of 20"-232,... | |

...vary as the sine of the star's latitude. This apparent motion of the stars arises from the velocity of light combined with the motion of the earth in its orbit. The sun is so very distant, that his rays are deemed parallel ; therefore let S'A . SB, fig. 116, be... | |
