CHAPTER III
THE SOLAR SYSTEM 1. The Solar System is better known to us, as the earth on which we flourish belongs to it. 2. The System is comprised of one sun (star), eight major planets, Mercury, Venus, Earth, and one satellite, Mars and two satellites, Jupiter and seven satellites, Saturn, its rings and ten satellites, Uranus and four satellites, Neptune and one satellite, and some 600 planetoids, varying in size from 600 miles in diameter to mere rocks. 3. The sun's diameter is 866,000 miles. Rotates every 606 hours. The length of time its current carries the sun over its orbit is unknown. The sun remains a melted mass; its vibration is maintained; has but little vapor and its theme reflected on the surface of its obsequious attendants which gives them heat and light. Dark spots caused by vapor becoming concentrated to the sun's surface; these spots change. 4. Mercury, the smallest major planet, also the closest to the sun. It is carried over its orbit about 36,000,000 miles from the sun, which requires 88 days to complete its course, and rotates once every 24 hours and 5 minutes. Its diameter is 3,000 miles and it has a suitable amount of vapor for animals and vegetables to flourish. |
