Retrograde Sun of NASA
'THE SUN'S PATH IN THE SKY ' "There is another astronomical effect you should know about that can change the time that the Sun is highest in the sky. This is a little hard to explain, but it also has to do with us watching the Sun from a tilted perspective. The Earth spins on its axis about 366 and 1/4 times each year, but there are only 365 and 1/4 days per year. This is because we define a day not based on the Earth's period of rotation, but based on the average time from noon one day to noon the next. Gradually over the course of a year the Sun appears to go 'backwards' (West to East) around the Earth compared to the far away stars (this is because we are really going around the Sun). Subtracting this 1 time backwards from the 366 and 1/4 times forward, we get the typical 365 and 1/4 days per year." http://imagine.gsfc.nasa.gov/docs/as...rs/970714.html Even those who claim to be just stargazing can't help but wonder why the indignities by institutions that people trust.Even allowing for thousands of clones who sound the same by creating whatever story they want with the approval of others,there has to be at least one other individual with the dignity and the intelligence to appreciate that no endeavor has ever suffered as badly as the astronomical one.
