^^^ You can use trig to find the angles between earth, a star and the sun at a certain time of the year. Then you can do the same thing at a different time of the year, say, 90 days away from the first. And then, when you use trig to compare the first angular measurements with the second, you find that the Sun is around 90 million miles away from the earth.
You can make these measurements and their comparisons with 10 different stars, the sun, and the earth. You don't have to rely on any single star. Your results will work out very well with many of the stars, and poorly with others, all because of their relationship to the earth. After all, some Southern Hemisphere stars can't even be seen in the Norther Hemisphere at certain times of the year... and vice versa.
If you happen to have a good telescope, or a good transit, or a very accurate sextant, these measurements will work out virtually the same. But you will need to be precise. Remember, a sextant was designed for making simple, basic measurements on a ship that might be rolling with the waves.
Then, if you throw in all kinds of other science, you will find out that the earth is, indeed, globular... and that the sun is indeed around 800,000 miles in diameter.
You are simply using all your incomplete FE science to attempt to delude people. I don't believe that you are doing this out of personal belief in what you are FE saying. I believe you are attempting to see how many people you can twist into believing something that is clearly understood to be wrong, and that you know exactly what you are doing.
All this does is to make you funny farm life to exist for reasons other than your personal belief in FE. It makes your FF life to exist because you are mentally twisted into trying to draw people away from the truth, while making it appear that you are doing so innocently.
