The two other terrestrial planets in our solar system with atmospheres would not support life. Venus is the hottest planet, with crushing atmospheric pressure. Anyone would die very quickly on its surface without a good space suit.
Mars has a very thin atmosphere, mostly carbon dioxide (a greenhouse gas), but essentially no free oxygen either.
There are other planets in our galaxy, orbiting other stars. We know what the atmospheres of some of those planets are like. So far we haven't found any much like earth, but that is because earth is small, and only recently have we developed the technology to find planets as small as ours.
The planets would slowly start to randomly go in directions, eventually colliding into the sun, or other planets.

my inability to go to other planets. and gravity
nothing would happen to other planets if the world ended because the planets are so far apart that the explosion wouldnt reach too other planets and take my advise. the world wont end right now because since when humans exist, the world is still young.
the sun is bigger than any other planets because millions of years ago meteorites smashed together to make the sun and to any other planets that did not happen
If the planets did not move in their fixed orbits they may dash each other.
If a planet doesn't follow its orbital path, then it may crash into other planets, moons and/or other object floating around in space.
They say that on that day all the planets will align with the sun and a meteor will go through all the planets including the sun
they wouldn't go around the sun and they wouldn't have lights at night.
Our nine planets orbit around the Sun. Other planets that are light-years away orbit around their suns (A sun is just a large star with planets). Hope this helped!
