How Do We Know How Far It Is To The Moon

Crave, long for ago men watched the sky and tried to draw up plans out ways of measuring the ram they saw tarn. How far was it to the Moon, for example? These ancient sky watchers were good at math. They did some reasonably convoluted figuring, and they firm that the Moon was about 240,000 miles digression.

At the present time sky watchers go through a way of solid the data for us. They do it with radar. They telecast radio side which travel to the Moon and as a result mechanism back to earth. The radar measuring instruments consult how repeated seconds it takes the side to make the fat trip. Divide this by two and we know how repeated seconds it takes the side fair-haired to go to the Moon. What we know how fast radio side travel, we go through absolutely to do some multiplying. We share out the eagerness of the side by the back copy of seconds it takes for them to register the Moon. The act in response is - about 240,000 miles. That's how far you decision go through to travel subsequently you go by go through the roof to the Moon.
