   No, it is about 0.5 degrees. It varies a little over a year due to the   
   ellipticity of the Earth's orbit. According to   
   https://flatearth.ws/sun-apparent-size, the size varies between 0.524°   
   and 0.5418°.   
      
   Near sunset the apparent vertical diameter is reduced by atmospheric   
   refraction. The horizontal diameter is not changed, I believe.
