The earth goes around the sun 1 time per year. Scientests have been studing the sun and how fast its moving and the sun seems to be speeding up!
It is estimated that the sun formed into a star about 4.57 billion years ago.
It really is burning out, but there is so much gas in it that it will really burn out after about ten billion years.
The energy of the sun results from atomic fusion of hydrogen into helium. Before nuclear fusion was understood (until the year 1939) the source of the sun's energy was not known. At that time it was thought that the sun was a huge ball of burning coal (where it got the oxygen to burn was not too clearly explained). A bit of math disproved this theory. First mass of the sun is about 1029 tones. Based on the amount of heat and light from the sun this amount of coal would be consumed in about the first 5000 years of its existence. Evidence proves the sun has been burning for the last seven to eight billion years. It would haven it would have been reduced to cold ash by now.
