The earth takes 1 year to complete one orbit.

In hours, that is

(1yr)*(365.25days/1yr)(24hrs/day) = 8766 hrs

One orbit is 360 degrees or 2pi radians

So, by proportion,

x/(24 hr) = 2pi/(8766 hr)

x = [2pi / 8766]*24

x = 0.0172 radians --------------answer.

That is about 1 degree.

(Umm, 360 degrees---365.25 days)

Edit:

Hey, what happened to the given R = 149 millions km?

Extraneous?

Or the question is not correct?

Or my solution is not correct?
