月亮有多大呢?这个问题似乎不大好入手.现在,科学家们通过精密的仪器已经能够比较准确的测量出月球的半径约为1730千米.但是如果不用这些精密的仪器,能否也可以估算出月球的半径呢?今天我就来向大家介绍这种测量月球半径的新方法. 不知道大家以前有没有注意过月蚀.当月蚀时地球在月球上形成影子,用照像机拍成照片,那么分析照片上的平面图形,就可以对月球半径做出粗略估计. How big is the moon? This problem does not seem to be a good start. Now, the scientists have been able to accurately measure the radius of the moon by a precision instrument is about 1730 km. But if you do not use these sophisticated instruments, can you also estimate What is the radius of the moon? Today, I’ll introduce you to this new method of measuring the radius of the moon. I don’t know whether or not you’ve noticed the lunar eclipse before. When the eclipse eclipse, the earth forms a shadow on the moon, and it is photographed with a camera. Then analyze the plane image on the photo to make a rough estimate of the radius of the moon.
