| Nov 24, 2019 at 15:36 | comment | added | David Hammen | Re The radius of the Earth orbit increases by about 15 cm per year. That figure comes from a 2004 paper that is almost certainly erroneous. The value based on solar mass loss from light, neutrinos, and solar wind is about an order of magnitude less than this. | |

| Nov 24, 2019 at 14:40 | comment | added | Shamaz | I understand that, but can’t we take of the energy of the system as just Earth energy as the Sun is much more massive than the Sun, in which case whatever happens to the Sun shouldn’t affect Earth’s energy. I read about the tides but some sources said this effect was marginal compared to the loosing mass. | |

| Nov 24, 2019 at 6:33 | comment | added | anna v | " the total energy of the Earth-Sun system remains unchanged " this assumption is wrong. Energy is conserved in closed systems, and the sun earth system is open . The grossest wrongness is that if we got all the energy radiated by the sun we would be fried to atoms. Only a small angle of the radiation fortunately reaches us. Other factors are also tides:the moon radius to earth enlarges because of the tides, and there will be sun tides hyperphysics.phy-astr.gsu.edu/hbase/…. | |
