Ignoring the huge about of energy to move a planet, if your moving your planet to another solar system without a worm hole it will take years and probably decades or centuries to get to your destination. Therefore, the probability is that freezing will cause significant damage to your planet. | |

| Jun 16, 2017 at 16:46 | comment | added | Peter - Reinstate Monica | Nitpick: Having a molten planet core lasts for cosmological time frames (the earth's core's heat is partly a leftover from back when). Planets are that big. But of course you need impractical amounts of energy to use the earth as " night storage heating", so heat is just one aspect of the answer "you can't because planets are too big". | |
| Dec 25, 2016 at 18:10 | comment | added | cybernard | @JanDvorak All matter contracts to some degree in the cold, and expands in response to heat. If the planet first freezes solid due to lack of sun, and then passes by a sun, the extreme temperature change could shatter the planet. The expanding and contracting also make for violent earthquakes, which could also fracture the planet into pieces. Like the whole, dip it in liquid nitro, pull it out hit it, and it shatters. You also risk, the planet being caught in gravity, your transportation method can't overcome. | |

| Sep 3, 2016 at 13:16 | comment | added | DevilApple227 | I know, I just give this as an example for how much it would take. And the energy density of oil is fairly high, higher than that of many other materials. On top of that, it's (relatively) easy to convert it into electrical energy, something that can't be said for most other energy sources. So in short, what you said i s correct: if you "eat" a star, and use that energy, then yes, it would be sufficient. But I don't see how you would manage to do this without catastrophic effects on Earth. | |
| Sep 1, 2016 at 22:08 | comment | added | MolbOrg | @DevilApple227 oil is not energy source. it is a mix of fancy chemicals barely different in energy from other chemicals. Be a big boy, like star, thermonuclear and we start talking. We talking about moving a planet, chemical energy in entire solar system is not enough to even make scratch on that task. I meant literary, in solar system there is not enough chemical energy to start that task by directly applying that energy to that task, instead of to invest it in to approaches for extraction energy from the star or a like. It is so because of gravity wells of most planets in our system. | |
| Sep 1, 2016 at 20:44 | comment | added | DevilApple227 | @MolbOrg Heating the entire planet on the caliber of a star is unfeasible, as the sun gives about 1353 Watts/square meter of energy. Powering this for any extended period of time would use up Earth's oil reserves pretty fast. As a point of reference, in What If, Randall Munroe showed that lighting up a quarter moon to the brightness of the midday sun via lasers on earth, ignoring atmospheric distortion, would use up Earth's oil reserves in 2 minutes. I can imagine doing this to the earth would be similar. | |
| Jun 24, 2016 at 20:12 | comment | added | MolbOrg | Undetected particle are undetected for reason week interaction with matter or small numbers of them. Small changes may be, but if we stay scientists, I'll say go for it, core will not freeze. Although sun magnetosphere interaction with core etc. But I do not expect something super exciting, which is significant and could not be fixed. But yes more preparation have to be done, not a problem. | |
| Jun 24, 2016 at 19:50 | comment | added | cybernard | @MolbOrg I hope we, all scientist, are not underestimating the suns effect on earth, and for the sake of your planet. The suns baths the earth in many known and unknown particles, it could be these particles are keeping the core molten. Your surface could be warm, but the core could still die. And if a fraction of the energy could keep it warm, if the planet was exposed to too much heat major changes could yet occur. | |
| Jun 24, 2016 at 19:15 | comment | added | MolbOrg | fraction of energy used in towing will be enough to heat and illuminate earth, not a problem here with freezing. Very like that diplomacy part. | |

added information about the planet could be serverly damaged due to earth quakes from large quanities of freezing water.
