Knowing astronomical informations quantitatively is more rewarding that just sheer qualitative.
In deep contrast many centuries back, it is now common knowledge of every relatively educated individual that this average size star – the sun is larger than our Earth and any other planet in the Solar System. But, we seem to settle at that information. What about pushing a bit further our learning into knowing this piece of astronomical information the astronomers does? Knowing our scientific erudition quantitatively is more rewarding than sheer qualitative information.
The ancient intellectual Greeks: Eratosthenes notably found for the first time an ingenious way of measuring the circumference of the earth without leaving Alexandria Egypt. He found that the earth was 39, 350 km just a little short of the modern value of 40,075. 16 km, a remarkable feat taking into account his time where modern scientific tools could be things of impossibility. From this information, the earth’s radius is obtained to be approximately equal to 6380 km, thus the volume of 1.1×1012 km3.
Subsequently, the sun was found to be approximately equal to 1.1×1018 km3 in volume. From this values we found how many earth’s would equal the size of the sun by dividing the sun’s volume by that of the earth’s- it is approximately equal to 1000,000 earths. Thus, the size of the sun can accommodate 1000,000 earths crammed inside it.
