How far is the sun from the earth? This is a question you might have asked yourself ever since you began asking about anything. In fact, for thousands of years astronomers had been asking the same question. But they had no way of getting an accurate answer because the sun was so far, far away. Now with the use of the radio telescope, they are able to give a very accurate answer: the sun is 92,956,000 miles away from the earth.
Can you imagine how far away that is?
The jet airliner today travels at a speed of 700 miles an hour. Imagine that you are flying to the sun in this airliner. You could make no stops for rest, no for gas or oil, because there would be no place for you to stop. You would fly day and night at such a speed. Yet by the time you arrived, 15 years would have passed.
