Moving dwarf planets to be moons

Post Reply New Topic

A wiki talks about moving dwarf planets to be moons of the outer planets Uranus and Neptune and terraforming them, terraforming black dwarfs by moving them into orbit around Sun-like stars (this probably would occur in the distant future, as no black dwarfs are thought to exist today) and even creating artificial "suns".

Sounds a bit far fetched to me.

Possible, but improbable; especially when considering the energy required to move a world like Ceres from its current orbit to one further away from the Sun, and without any interference from the gravity of Jupiter or Saturn.

I don't think they're suggesting moving Ceres. They're talking about the further away dwarf planets like Pluto and Eris moving them closer to the Sun by making them moons of Uranus or Neptune and terraforming them.

possible in theory, but terraforming in and of itself is a long shot with our current technology levels.

moving a planet is just not practically possible yet; the fuel required to do so is so mindbogglingly large, there is no way we can lift that amount off of the earth (assuming we even have enough), so we'd have to set up fuel mining on other celestial bodies (like the moon; which has been talked about before).

getting the fuel in position isn't the problem, and the theory of moving a planet is the same as moving an astroid, just bigger, so it's all theoretically possible.

just don't expect to see it within our lifetime

Same problem. It takes energy - lots of energy - to decelerate that much mass and drop it into a lesser orbit. Any change in velocity requires it. F=ma, after all.

I wonder whether moving Eris into orbit around Neptune would be cheaper than blowing it up. It might be an interesting option to restore Pluto's planet status.
