The Moon may thus be described as following an elliptical orbit around the Sun at a distance of some 150 million km, superimposed upon which there are small monthly oscillations. Because the gravitational force is never directed away from the Sun, the orbit, despite these oscillations, is ...

one in the direction of the Moon and one directly opposite. The effect is much stronger in the ocean water than in the solid crust so the water bulges are higher. And because the Earth rotates much faster than the Moon moves in its orbit, the bulges move around the Earth about once ...
The phases of the Moon are something you've noticed from time to time in the night sky, but perhaps never really thought about. What causes the phases of the Moon is really nothing more than the Moon's orbit around Earth, Earth's orbit around the Sun, and how this all appears from ...
Sun changes; we see this as the cycle of the Moon's phases. The time between successive new moons is 29.5 days (709 hours), slightly different from the Moon's orbital period (measured against the stars) since the Earth moves a significant distance in its orbit around the Sun in that ...
14 The moon seemed lost. Having abandoned the course of its orbit, it no longer knew where to go; it let itself be transported like a dry leaf. Sometimes it appeared to be plummeting toward the earth, at others corkscrewing in a spiral movement, and at still others it looked to be ju...
People on Earth could only see one face of the Moonbecause it rotates around on its own axis in exactly the same time it takes to orbit the Earth.The far side of the Moon can only be seen from spacecraft. 月球昼夜温差极大 由于月球表面几乎没有大气层,缺少了大气层对于温度的调节之后,月球...
