does the horizon on other, bigger planets (or suns) look the same as earth’s? How much higher do you have to go to see it curve?

Question

What happens with bigger planets or suns if you stand on them and look as far as you can? Does it look the same? A straight line, but much further away? So will you still be able to see objects hundreds of kilometres away because they’re before the curve? Thank you!!

Answer 1

ELI5: If that planet has air and dust and fog like Earth does, it will look a lot like what you see here! But if the planet had NO air, and no trees or mountains were in the way, you could see really far!
