...suppose the two to be really of the same size, their distances from us must be in the ratio of 57.3 **to 1, because light diminishes as the square of the distance of the luminous body increases.** Of the absolute magnitude of the stars, nothing" is known, only that many of them must be much larger... | |

...the star of the sixth magnitude is fifty-seven and one third times farther from us than Sirius is, **because light diminishes as the square of the distance of the luminous body increases.** By the same reasoning it may be shown, that if Sirius were placed where the SUII is, it would appear... | |

...324 times greater than that of a star of the sLxth magnitude. Nothing is known of the absolute size **of the fixed stars ; but the quantity of light emitted by many of them shows that they must be much** greater than the Sun. Sirius is nearly four times larger, and many stars must be infinitely larger... | |

...suppose the two to be really of the same size, their distances from us must be in the ratio of 57'3 **to 1, because light diminishes as the square of the distance of the luminous body increases.** So many of the stars have proper motions altogether independent of the annual rotation of the earth... | |
