Are there planets underneath earth

There is none belowe earth, or above it. This s because in space tuere is realy no direction. So there could be one under but it realy wouldnt be. It also depends on your position on earth. And we also dont know because there are (probably) no telescopes in antarctica, whicg is where they would need to be. So just since the the universe is never going to stop growing i would say yes, and a small definently.

there are planets all over imagine we live in a 3d world, particles were ejected in all directions from the big bang so yeah everywhere you loook, .....take a look at some of the shapes of the universe that scientist have come up with its very interesting

Earth turns.
From any given position on it, 'below' sweeps a pretty wide swath of territory.

Go to school, learn about geography and general logic and then ask this question.
