Secondly, that potential energy is not what is required to keep them in those orbits; rather, it is the energy you would need to supply to pull them OUT of those orbits and out of the solar system. Third, a formula for gravitational potential energy is not an equation for conservation of energy. > > GM mpl dm E > MER 1.3271E+20 3.3022E+23 57,909,231,029 3.7839E+32 > VEN 1.3271E+20 4.8685E+24 108,209,525,401 2.9855E+33 > EAR 1.3271E+20 5.9736E+24 149,598,319,494 2.6497E+33 > MAR 1.3271E+20 6.4185E+23 227,943,771,564 1.8685E+32 > JUP 1.3271E+20 1.8986E+27 778,342,761,465 1.6186E+35 > SAT 1.3271E+20 5.6846E+26 1,426,714,892,866 2.6439E+34 > URA 1.3271E+20 8.6810E+25 2,870,633,540,862 2.0067E+33 > NEP 1.3271E+20 1.0243E+26 4,498,393,012,162 1.5110E+33 > PLU 1.3271E+20 1.2500E+22 5,906,438,090,764 1.4043E+29 > > Total in joules 1.9801E+35 > -- Odd Bodkin --- maker of fine toys, tools, tables
