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.
NO- People have found water on other planets but there is no life there.
there going to take it out of our planets list
No.
Short of going to other planets it cannot be proven, unless of course, they come here.
When it is completed, it will transport and help people get to planets for example if a probe is going to mars its going to stop and prepare for the trip and other stuff.
because the gravatational pull from the sun and other planets keep the planets going in a circler motion and not bumping into each other.Answerbecause 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.
Because we can see the nearest planets through telescopes and for those much further away we can detect them by their effect on other planets and stars.
None that we know of.
People want to explore other planets to expand our understanding of the universe, to discover if life exists beyond Earth, and to potentially find resources that could benefit humanity in the future. Exploration of other planets also allows us to push the boundaries of science and technology.
The inner planets are different from the other planets mainly because
yes some
Some people believe that spaceships from other planets have visited Earth, but no one has ever been able to prove it.
