The things that pop into my mind in the middle of the night…
Those evil but incredibly advanced at science Alpha Centaurions have decided that they need to add another star to their system (I don’t know why, keeping up with the Jones, probably) and have decided our Sun is just the right size and hue to fit their decoration scheme.
So they send out their SuperSpace Tug with the latest AmazoTractorBeamThingy. It latches onto the Sun (yes, quite a tricky challenge, but as I said they have advanced science) and start dragging it home.
What I want to know is, what will happen to the planets of our solar system?
Will they be dragged along by the Sun’s gravity, with their orbits more or less disturbed/the same?
Will only some planets go along (the closest ones, maybe) while the rest are lost? Or only the ones that happened to be moving in approximately the ‘right’ direction at the time the Sun gets yanked off?
Or will they all be left in the cold and dark? <sniff>
If a planet is left behind, I assume they will head off in whatever direction at whatever speed they happened to be traveling at when this, ah, disruption occurred? If so, what’s their likely fate? Will they travel ‘forever’ or eventually smash into something, or end up orbiting some other star?
Drawing on a knowledge of physics that consists of one course in High School mumblety years ago, I’m guessing that what mostly counts is how fast the Sun is pulled away, plus the mass of the Sun and a particular planet and the distance between them.
Let’s say that it will take 100 (Earth) years for the Evil ACs to haul our sun the 4.3 light years.
Some googling got me:
Distance from Earth to Sun: 149.6 million kilometers (average)
Mass of Earth: 5.976e24 kg
Mass of Sun: 1.989e+30 kg
But I don’t know how to proceed any further.
