The metaphor of the solar system as a "colony" offers a distinct implication about its structure and relationships by emphasizing a sense of shared membership and a central organizing force. It suggests that Earth is not an isolated entity but rather one component within a larger, interconnected group. This "colony" is explicitly defined as consisting of the eight planets, including Earth, and the sun, which together form the Solar System [1, 3, 5]. The metaphor implies a familial or community-like structure, where each member, despite its individual characteristics and immense distances from others, belongs to and revolves around a common center.
Compared to simply stating that planets orbit the sun, the "colony" metaphor highlights the idea of Earth as a member, not the sole focus of the system. It implies that the planets are akin to a group of inhabitants or dependents under the influence of the sun, which acts as the core of this collective [1, 5]. The passage notes that the members of this "little colony" are at enormous distances from one another [1]. The metaphor, therefore, conveys both a sense of unity within the system and the vastness of its scale, even within this…

From the book
ies are called _planets_, or wanderers. There are eight of them, including the Earth, and they all circle round the sun. Their names, in the order of their distance from the sun, are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and of these Mercury, the nearest to the sun, is rarely seen by the naked eye. Uranus is practically invisible, and Neptune quite so. These eight planets, together with the sun, constitute, as we have said, a sort of little colony; this colony is called the Solar System. The second class of heavenly bodies are those which lie _outside_ the solar…
ets are held to their orbits. Circling round the earth, in the same way as the earth circles round the sun, is our moon. Sometimes the moon passes directly between us and the sun, and cuts off the light from us. We then have a total or partial eclipse of the sun. At other times the earth passes directly between the sun and the moon, and causes an eclipse of the moon. The great ball of the earth naturally trails a mighty shadow across space, and the moon is "eclipsed" when it passes into this. The other seven planets, five of which have moons of their own, circle round the sun as the earth…

THE COMPARATIVE DISTANCES OF THE PLANETS (Drawn approximately to scale) The isolation of the Solar System is very great. On the above scale the _nearest_ star (at a distance of 25 trillions of miles) would be over _one half mile_ away. The hours, days, and years are the measures of time as we use them; that is: Jupiter's "Day" (one rotation of the planet) is made in ten of _our hours_; Mercury's "Year" (one revolution of the planet around the Sun) is eighty-eight of _our days_. Mercury's "Day" and "Year" are the same. This planet turns always the same side to the Sun.] [Illustration: THE…
ivilisation. Before our time the problem could be considered only from the imaginative or the speculative point of view. Although we can to-day attack it to a limited extent by scientific methods, it must be admitted that we have scarcely taken more than the first step toward the actual solution.... What is the duration of the universe in time? Is it fitted to last for ever in its present form, or does it contain within itself the seeds of dissolution? Must it, in the course of time, in we know not how many millions of ages, be transformed into something very different from what it now is?…
More questions about this book
- The text states that astronomy's picture of the Universe is "imperfect" and "uncertain." How would you explain to a curious non-scientist *why* this is the case, considering the advancements of science, and what fundamental challenges does this inherently present to astronomers?
- Simon Newcomb calls the "structure and duration of the universe" the "most far-reaching" problem. If you had to explain to someone *why* understanding the universe's ultimate fate and design is considered more significant than other astronomical discoveries, what core ideas would you emphasize from this excerpt?
- The author notes that we have moved from "imaginative or the speculative point of view" to scientific methods, yet have "scarcely taken more than the first step." What characteristics define this "first step" in scientific inquiry regarding the universe's grand questions, and how might future, more advanced steps differ in their approach?
- How does the question of whether "the stars form a system" directly influence the conclusion about the universe's "duration" and potential for "dissolution" or "transformation," as presented in the text? Could you articulate the logical connection between these two ideas for someone unfamiliar with astrophysics?
