WebSep 2, 2016 · With essentially no change to distance from the sun, and only relatively small changes in tilt and eccentricity, Earth's temperature can fluctuate from a current 15 °C global average to about 5 °C as it goes in and out of ice ages. WebJun 12, 2016 · I have considered the eccentricity of the planets and thought of using it to determine uncertainty. So then I would have: Earth distance from Sun = ( 150 × 10 6 ± 2.5 × 10 6) k m. As Earth's eccentricity is around 0.017. So I am wondering if this would be the right way to determine the uncertainty of the radius of the orbit distance. eastern percussion module
