quick question about the sun.


Recommended Posts

Hi, the Sun doesn't move but the Earth orbits the Sun and the Earth rotates of course. As a result of Both these, on Earth we have to 'add' roughly 4 minutes of time to one Earth rotation per day. 23 hours 56 minutes is one Earth rotation so we add 4 minutes to account for Earth's movement around the Sun and then the Sun crosses the meridian at roughly the same time every day. The net result of this is that the Sun moves as you say with respect to the celestial sphere ( our view of the stars).

No, do you mean the earlier and later rising of the sun?

If so that is caused by our tilt.

Never thought of it that way but moving by a degree a day (or whatever) is I suppose one way of thinking about it.

If you are interpretting 365 days and 360 degrees in a circle that is probaly chance more then anything.

The Babylonians used 360 divisions in a circle almost simply because there are more numbers that divide nicely into 360 then other numbers.

From early PC games there was one called Star Trek which for whatever reason decided to use 400 divisions (1 division being a Grad). You had to tell the Enterprise to turn by 100 to get it to make a left/right turn, not 90.
