Hi Mooeypoo, I actually agree with you It doesn't make much difference to science. It is interesting though, at least to me. Back to the topic... This one

Hi, It's tracing a circle in the sky. Not sure how it matters what else is going on if I'm only looking for the total angle traced in the sky by the Sun. Mark

Hi, Thanks for your response. Of course, we know that the Earth moves around the sun. But from a reference frame of standing on the Earth, the Sun is travelling through the sky. Not this. Just how much angle the Sun travels through that sky in one year to get back to point X. Right, as I mentioned above. But we're taking the reference frame of standing on the Earth. Of course it is an apparent movement. Mark

Right. So, I get for my calculations 473040000 arcseconds that the Sun travels through the sky in one year. I did 1296000'' x 365 days. Corrections welcome!

Standing on the Earth in one spot all year....

In any case, it's not up to me. It's up to the moderators of this forum if they want this topic to be discussed. Of course, if they don't want to discuss this topic, there is nothing more for me to say.

I'm still just looking for the number of arcseconds, and thought that I would get more help here. Seriously, that's all I want to find out in this discussion. This, to me, seems a basic of astronomy. Yes, I have my own answer, but I want others to confirm the number.

Hi Everyone, I'm wondering how many arcseconds the Sun "travels" in one Tropical Year. I think it travels 1296000 in one day. Mark Merged post follows: Consecutive posts mergedSo, this is from the reference point of someone standing on the solid Earth in one spot all year. We could say that the sun starts at 90 degrees, goes down and up and back to 90 degrees(of course as the seasons change, the angle changes but that doesn't effect the calculation of angle travelled, and it does this 365 times, eventually coming back to the same position in the sky. 360 degrees times 365 days. Here are my calculations: One year: 131400 degrees, which is 7884000 arcminutes, which is 473040000 arcseconds. I believe that is 473040000 arcseconds of angle traveled by the Sun from the reference point of someone standing on the solid earth in the same spot all year. If someone could check my numbers, I would appreciate it. Mark
