its a globe. im experienced in astronomy, especially celestial mechanics and the associated equations. the solar system observations align (nearly) exactly with the equations- which are all based on elliptical paths with the earth modeled as a sphere. when you add in the gravitational and electric effects, the celestial dynamics are extremely well correlated to visual and irradiation observations. comes from that time I worked at a solar observatory.
