I'm impressed with this informative video about the history of the Solar System, including its future. However, you forgot the dwarf planets, including Pluto.
Quantum Tunneling Event #1: EVERY solid object becomes a perfect sphere because over extremely long stretches of time, even solids flow like liquids. Quantum Tunneling Event #2: All elements lighter than iron slowly fuse into iron, and all elements heavier than iron (including lead) slowly decay into iron. Why iron? Because iron is the most stable form of ordinary matter. Quantum Tunneling Event #3: All of these spheres of pure iron will become spheres of equally-pure neutronium. Neutronium is literally a mass of neutrons stuck together, which is the main constituent of neutron stars. Quantum Tunneling Event #4: Every sphere of neutronium becomes a black hole; and all of these black holes then evaporate via Hawking radiation. Beyond this point, the universe will be left as a cold, expanding place that contains nothing but electrons, positrons, neutrinos, anti-neutrinos, and photons.
