We use a piece of cardboard with a small hole in it which slides up and down a yardstick to show that it is possible to determine the eccentricity ≈0.039±0.006 of the Moon's orbit. A typical measurement uncertainty of the Moon's angular size is ±0.8 arcmin. Because the Moon's ...
Participants Eleven hundred adult, dependent smokers who called the New Zealand Quitline between March 2006 and May 2007 for support to stop smoking were randomized to 2 weeks of nicotine patches and/or gum prior to their target quit day followed by usual care (8 weeks of patches and/or gum...
Moon/ orbital eccentricityMercuryoriginMoondynamic captureEarth/ A9620B Lunar origin, evolution, and age A9630D MercuryA NUMBER of mechanisms for the formation of the Moon have been suggested; fission of the Earth, precipitation in a hot gaseous silicate atmosphere, independent formation in orbit ...
Eccentricity is a measure of how an orbit deviates from circular. A perfectly circular orbit has an eccentricity of zero; higher numbers indicate more elliptical orbits. Neptune, Venus, and Earth are the planets in our solar system with the least eccentric orbits. Pluto and Mercury are the pl...
The surface of the Martian moon Phobos exhibits two distinct geologic units, red and blue, characterized by their spectral slopes. The provenance of these units is uncertain yet crucial to understanding the origin of the Martian moon and its interaction with the space environment. Here we present...

In order to compute with a reasonable accuracy satellite orbits subjected to perturbations byJ 2, the Sun, the Moon and airdrag, a first order expansion is
The moon's low eccentricity results in a nearly circular orbit around Earth. 7 Concentricity The characteristic of having a common center in geometric shapes. The concentric rings of Saturn are visible through telescopes. 6 Eccentricity A measure of deviation from circularity in ellipses. The eccentr...
Eccentricity resonances between the secular motion of an Earth satellite's orbit and the longitudes of the Sun and the Moon are studied within a Hamiltonia... S Breiter - 《Celestial Mechanics & Dynamical Astronomy》 被引量: 48发表: 1999年 The dynamical structure of the MEO region: long-te...
