If it just lost momentum, it would fall onto the sun, but it would take about 29 years to fall, meaning it most likely fell into another planet possibly derailing it, too, and so on. And this doesn't consider that its gravitation would likely start affecting orbits long before it actually hits anything
My first thought was. If a planet the size and location of neptune just vanished.
What effects would that have on the rest of the solar system. Given Pluto was found due to its effect on neptune I think. And this is a relatively small mass on a larger one.
I'd be very interested to hear opinions on what the sudden disappearance of a planet would do.
Just to put everyone's mind at rest. I am not an evil scientist working on quantum teleportation.
That said. Feel free to consider other planets. ... such as jupiter. ;)
Your forget that the sun isnt stationary. Our whole solar system would slowly move away from anything truly stationary while we continue our orbit of the milky way. It would take a good while but after a few years neptune would be pretty far from the sun. If it got stopped while in the path of the sun tho, it might just get run over by the sun and we would all die.
This would have some amount of effect on the earth, though I'm not knowledgeable enough to say what the effect would be. I could imagine the result being anywhere from "it's measurable with scientific instruments" and up to "all life on earth will die within hours".
Off the top of my head iirc Neptune prevents a huge amount of large meteors from hitting the earth, so i think for that reason alone it would lead to earth being frequently hit with meteors that each cause nuclear weapon level of destruction.
EDIT
Actually Jupiter is the planet that protects us from asteroids, so that specific effect probably wouldn't be in play
Them's fighting words, early Einstein. I'm pretty sure if you run the universal gravity equation that the distance and mass of Neptune would have minimal effect when moving away from earth, if any noticeable effect at all.
The premise of the comic is that some supernatural force could do something completely inexplicable to science and I'm saying that's not how science works.
