The result for GM in each instance is 1.32716E+20. You may need to consider more adjustments. The giant planets affect the orbital periods of the inner planets. It's a pretty big effect -- equivalent to adjusting the mass of the sun by 1/3 of Jupiter's mass. I.e. unless taken into account the solar mass can only be accurate to ~4 sig figures. >... -- -- http://www.ec.gc.ca/adsc-cmda/default.asp?lang=En&n=188031DB-1 The time series graph (below) shows that, when averaged across the nation, annual temperatures have fluctuated from year to year over the period 1948- 2014. The linear trend indicates that annual temperatures averaged across the nation have warmed by 1.6?C over the past 67 years. <http://www.ec.gc.ca/adsc-cmda/188031DB-BA85-4FB5-9923-46076E0E4C56/ CTVB_annual_2014_temp_graph_e.jpg>
