Is this even possible for a planet to stay alone without a star system? I know that stars and planets are formed together, and the materials to make the star make the star, and the leftover forms the planets, but can a planet be formed without the central star(s)? and what will happen to a planet if the sun exploded (and didn't turn into white dwarf) and neptune is still alive? Will neptune stay in it's solar orbit or just drift into space until it gets into orbit of some other star?
