Because the earth rotates (自转) on its axis once every twenty-four hours, earth-based astronomers see the stars hurry across the sky each night. The moon rotates on its axis only once a month. To astronomers on the moon, the stars will appear to stand almost still. Moon-based ...
Theearth rotates (转动) on its axis(轴) from the west to theeast, and at the same time revolves(围绕 …… 旋转)around the sun. The earth is now 4.5 billion years old. Themoon is its satellite.The radius(半径) of the earth's equator(赤道) is6,378.137 km, the polar (极) radius ...
The Moon always keeps the same face towards the Earth. This happens because the Moon rotates on its axis at the same angular speed as it orbits the Earth, a phenomenon known assynchronous rotationwhich is a special kind oftidal locking. Although the Moon is spherical, the hemisphere that fac...
The moon rotates on its axis while orbiting the earth; it just does one rotation on its axis for each revolution it makes around the earth, so it keeps the same side facing the earth. There's an old saying calling the back side of the moon (the side we never see) the "dark side ...
(4)C.根据"The Moon goes around the Earth,and rotates on its axis as it revolves.It takes about 28 days to revolve,and it takes the same length of time to rotate.(月球绕着地球转,绕着地球自转。围绕地球转大约需要28天,自转的时间也一样长。)"可知这里说的是有关月球围绕着地球运转的知识,...
Looking at the Moon, you only see one side. The Moon rotates on its axis at the same speed as it orbits around the Earth. When Apollo 11 carried Neil Armstrong, Buzz Aldrin and Michael Collins to the Moon, they landed on the far side of the Moon, which we do not see. Communication...
When the moon is full, it's night-time on the far side. [China's Chang'e 4 Moon Far Side Mission in Pictures] The reason we only see the one face is because of a phenomenon known as "tidal locking." The moon rotates on its axis roughly once every 27 days, which is the same...
Aside from this type of motion, the Moon also rotates on its axis. Questions What causes the Moon to keep on moving? Differentiate rotation and revolution. How long does it take for the Moon to orbit the Earth and rotate on its axis? Explain why we don't see the dark side of ...
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...
And while the Moon rotates on its own axis, the speed at which it rotates (aka. it’s sidereal rotation) is very slow. In fact, it takes the Moon the equivalent of27.3 Earth days to complete a single rotation on its axis, the same amount of time it takes to complete a single orbit...
