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 and other small bodies. But what if there were more planets (in this case, 26 — as many planets as Latin letters), and the Solar System was different as a result? And also, the Sun was a trinary star system, with OTL’s Spica binary system (known as Spica and Azimech ITTL) joining it?

Changes

 * The Sun would be a trinary star system, consisting of the main yellow star known as Sol, and two blue stars (located in Virgo IOTL) known as Spica and Azimech, which ITTL, became a contact binary.
 * 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 also have more continents and moons, including a habitable moon known as Selene. See What if Earth was bigger? for more info about this.
 * There would also be a “Counter-Earth” or “Antichthon”, orbiting (not quite) on the opposite side of the Sun from Earth, of similar size to Venus and with a moon (much like the OTL Luna/Moon) known as Erinye. See here for Antichthon’s main inspiration.
 * There would be a third 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.
 * Mars would have a third moon known as Bellona.
 * Between Mars and the Asteroid Belt, there would be a green gas dwarf planet known as Juno.
 * There would be a binary planet, Prometheus and Epimetheus, between Saturn and Uranus, which would share their moons, forming the Japtoid cluster.
 * 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.
 * Between Neptune and Cupido would be the Kemtoid belt, with objects named after Egyptian deities.
 * Planet 9 (actually Planet 23 in this case) would be real, not just hypothetical, and would be named Erebus.
 * Beyond Erebus would be 3 supergiant planets (or, slightly more accurately, dwarf stars): Tyche, Nemesis, and Wormwood. Tyche would be a single planet, while Nemesis and Wormwood would form a binary system.
 * Due to the number of days in a week being based on the number of planets known to ancients, there would be 13 days in a week: 8 weekdays and 5 weekends. See here for name suggestions.
 * The dwarf planets would all be the same: most of them would be located between Poseidon and Erebus, except Ceres which would be located in the asteroid belt, and Sedna which would be located beyond Nemesis/Wormwood.
 * One difference is that Eris would have been discovered much earlier, in 1949. As a result, Pluto’s reclassification and the invention of the “dwarf planet” term occurred in 1953 ITTL.
