Earth is intimately tied to the star around which it revolves, the Sun, and the satellite that revolves around Earth itself, the Moon. Without the Sun, of course, life on Earth simply could not exist, not just because of the need for light but to an even greater degree because of the ...
Movable didactic element to mechanically represent the movements of rotation of the earth and the moon on themselves and of translation of the moon around the earth, and of the earth and the moon around the sun; so that the orbits of the earth and moon are elliptical. It is characterized ...

When the moon is in its "new" phase, it passes between the Earth and the sun, so the side facing the Earth appears dark. To find out when and where you can see the next solar eclipse, check out oursolar eclipse guide. Occasionally, the moon's orbit lines up with the sun in such ...

In this framework, the contribution of the gravitational "magnetic" field of the sun to the tidal force acting on the earth-moon system is determined. Furthermore, the main relativistic perturbations in the lunar motion are estimated.关键词: Theoretical or Mathematical/ celestial mechanics Earth ...
