wunder beta🪐 The Story of the Solar System
You are being told you cannot do astronomy without a great telescope. Chambers’s answer is a painter at an attic window, with two and a half inches of glass.
What you’ll learn
- An attic is enoughShow that Chambers’s book is a practical 1895 tour for two- to four-inch telescopes, and that its first lesson is geometry: inferior planets stay near the Sun.Goldschmidt’s attic is the moral. Companion to The Story of the Stars. Mercury 27°, Venus 47°, never in opposition. Eight major planets; hundreds of minor ones between Mars and Jupiter.
- Holes in the Sun, air in the wayWatch Wilson’s 1769 spots behave as cavities, keep the Sun’s energy as an unknown, and put the observer inside refraction, twilight, and a jagged lunar terminator.Spots have nucleus, umbra, penumbra and act like holes. Light and heat: origin unknown. Copernicus missed Mercury in river vapour. The Moon’s terminator is landscape.
- Other centres, then a public cometFollow Galileo’s four Jovian moons and Huygens’s ring, then watch Uranus and Neptune join the map, without taking Chapter I’s retrograde-orbit slip as fact.Four moons you can follow; a fifth you cannot. Saturn’s ring was an anagram before it was a picture. Herschel’s comet became Uranus; Neptune was calculated. A body beyond Neptune stays a question. Look tonight.
Questions this course answers
What does Chambers offer as proof that a small telescope is enough?
The preface points to Goldschmidt at Fontenay-aux-Roses, 2½ inches, fourteen minor planets, as the standing answer to anyone waiting for a large telescope.
Why can you never see Mercury or Venus at midnight opposite the Sun?
Inferior planets reach at most about 27° and 47° from the Sun. Opposition is a geometry reserved for superior planets.
Match each claim to what the book actually does with it
Wilson’s cavities and Huygens’s ring are observations. Copernicus is a caution about air. The retrograde-orbit sentence is a slip; the satellites are the retrograde bodies.
What could a small telescope of Chambers’s type actually follow on Jupiter?
Chapter IX: four old satellites shine like 7th-magnitude stars and are the amateur’s stock-in-trade. The fifth, 9 September 1892, needs one of the largest telescopes.
How does Chambers treat a planet beyond Neptune?
Chapter XII: there seems some evidence, better understood with long-period comets, but little progress toward a solution. He does not announce a ninth planet.
