Are people going to other planets?
i don't think they are. because if there were people going to different planets then wouldn't it be a huge thing around the globe, like the oil spill fro an example. and wat planet in our solar system is livable/breathable. possibly in the way back future, but today its a no for sure.
because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other. Answer because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other. the planets each have defined Elliptical, not circular, orbits that remain constant because of gravitational pull of the sun and from each other. Pluto does have such an elliptical orbit that for a time it was closer than Neptune, but they will never collide with their current paths.
people r 97 percent sure that there r no lives on other planets but there is only 3 percent chance that there r, but if u think, there r no water on other planets, earth is the only planet that has water, so how can other people survive on other planets if there r no water, people need water to survive, just think about it! :)
