What if there were more planets in the Solar System?

We all know that the Solar System has 8 planets (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune), 9 dwarf planets (Ceres, Orcus, Pluto, Haumea, Quaoar, Makemake, Gonggong, Eris, and Sedna), and millions of asteroids. But what if there were more planets, and the Solar System was different as a result?

Changes

 * There would be another planet orbiting the Sun closer than Mercury, known as Vulcan.
 * Venus would have a moon known as Neith.
 * Earth would be “Super-Earth” sized, but still habitable. It would have an additional moon known as Lilith.
 * There would be another habitable planet between Earth and Mars, about the same size as OTL Earth, known as Minerva. It would have a moon known as Ariadne. The lifeforms on Minerva would be similar to the speculative biology project Snaiad.
 * The Hamburg School turned out to be right: there were 8 planets beyond Neptune. Not just dwarf planets, but actual planets. In order of distance from the Sun, their names are Cupido, Hades, Zeus, Kronos, Apollon, Admetos, Hera, and Poseidon.
 * Planet 9 (actually Planet 19 in this case) would be real, not just hypothetical, and would be named Erebus.
 * Beyond Erebus would be 3 dwarf stars: Tyche, Nemesis, and Wormwood.
