Moving earth like a space ship is so dumb!
1) An asteroid that hits the earth and kills all the dinosaurs, didn't budge the earth from it's orbit.
2) The moon creation even that suggests that 4.5b years ago an object the size of Mars collided with the earth to create the moon. Yet it didn't budge the earth from it's orbit around the Sun.
3) The Mass of the earth is 6,000,000,000,000,000,000,000,000 kg. the force required to move that object 1meter per second is Force = Mass * Acceleration. or 6 * 10^24 newtons. So to change the speed of the earth by a nearly useless 1m/s or 2.25 MPH, would require the energy of 142 million megatons of TNT. Over 10,000 times the total amount of all the worlds nuclear weapons. Or in other words if we detonated every single nuke in the world in the same place at the time that would be enough to budge the earth .000225 MPH or 14 inches per hour.
4) Even if there was an energy source that abundant to move the earth to Jupiter much less another star light years away, we would simply not need a star at all. We could just set the earth to a further orbit from the sun, and use all that propulsion energy to substitute for the sun.
5) Lets be ridiculously generous and say the earth could reach Jupiter in 1 year 365,000,000 miles away, that would very roughly equate to a speed of 41,000 mph (which is way faster than the 14" per hour all the nukes in the world could move the earth). To travel to our next nearest star (alpha centauri) is 25 trillion miles away, that would take 70,000 years, or if we used the 14" per hour speed it would take 17,580 billion earth years.
6) The Hiroshima nuclear blast was 20ktons of TNT. So imagine what 700,000 of those would do to the surface and atmosphere of the Earth. And that's to move 14" an hour.
