国际空间站上的一名船员拍摄了位于埃尔巴岛上的北部地中海的形象,意大利城镇Piombino和蓬塔阿拉图像的城市灯光正确。在海面上拍摄月球的反射,moonglint揭示了海面上高度复杂的图案 - 夜晚相当于sunglint。最强烈的反射在月球的中心附近,这使得厄尔巴岛周围的海面变亮。但是在从空间看的复杂模式中,海面的黑暗区域甚至使像E...

In a first approximation the motion of the Moon around the Earth can be described by Kepler's laws of planetary motion, the Moon moving in an elliptic orbit having the Earth at one focus. But the departures from this description, called perturbations, are much greater for the Moon than for...
