What do あなた think will happen to the gas gaints and Pluto after the Sun dies 5 billion years from now since the inner planets have been burned によって the Sun?
Due to the intense heat they might get vaporised または if there is no gravity they may wander off into 宇宙 and perhaps find another 星, つ星 to orbit although it will be very far :)
Depending how close mars/earth would be to the white dwarf of a sun, the 2 closest planets may stay in orbit of the dying white dwarf. The larger and もっと見る outward planets would float into everlasting space, no longer ruled によって a 星, つ星 または gravity unless they happen acrossed another star, black hole, または something else that's gravity would start the planet's dancing orbit. Most likely, they would crash into other wondering planets, creating dust and metal particles, and thus in turn creating new planets in the universe.
