...description of areas, it follows that the momentary angular velocity of a planet about the sun also varies inversely as the square of the planet's distance from the sun. Thus, the light and heat momentarily received by a planet vary directly as the planet's angular velocity... | |

...different elliptic orbits, the space through which a planet is pulled in a unit of time by the sun varies inversely as the square of the planet's distance from the sun. Therefore the law of gravitation is true of the sun attracting the different planets in their different... | |

...in the distances from the sun will account for much. The solar gravitation or tide-producing force varies inversely as the square of the planet's distance from the sun. Taking this force at the earth as unity, its value at Venns is 1-9 and at Mercury 6-7. Evidently the... | |

...planet is directed toward the Sun. 2. From Kepler's first law: The Sun's attraction for a given planet varies inversely as the square of the planet's distance from the Sun. 3. From the harmonic law: The Sun's attraction varies from one planet to another inversely as the square... | |

... varies inversely as the square of the planet's distance from the sun. There is a slight error in Nichol's statement that ' by an appropriate choice of an eccentric circular orbit the sun's motion relative to the earth or to any planet,' (or, which...
