The Rogue Earth -team is looking for your ideas and comments. Join and show your support for Rogue Earth.  Close to the sun?How will you explain away that people will cook? Also, that isn't how slingshoting works. You gain the orbit speed, nothing else. It won't do any difference. Mercury would be useful as a slingshot though. As long as the orbit is taking it towards the other planets at the moment. The whole concept is tricky for a Hard SF story. The planets would need to be perfectly aligned along the vector and everything. I have heard GELF before, but I can't remember what it means. |

GELF: Genetically Engineered Life Form
It is the gravitational waves from deep space that change the Earth's orbit into a long ellipse. The Sun itself is gravitational the slingshot for the Grand Tour during the next alignment. And the encounter with Mercury is on the way in towards The Sun. The inhabitants of Mercury are silicon life, comfortable at temperatures of liquid rock. But the Earth, of course, requires the hasty construction of a giant parasol for protection.
And Mercury is small. It wouldn't help much, and probably loose it's orbit in the process. I don't know about Venus though. Does it have more mass than Earth?
