Growing up I was always taught of nine planets, we even had a clever mnemonic used to remember them, “My Very Excellent Mother Just Served Us Nine Pizzas.” The first letter in each word denotes the name of one of our solar system’s planets in order: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto. In the year 2006 the International Astronomical Union ruled that Pluto should be categorized as a dwarf planet and is no longer to be recognized with the larger planets. I have been upset about the ruling on Pluto for years, since it means my “mother serves us nothing,” but recent debates look to change how we see our planets. Over the past year there has been a push to revise the way we classify planets, which would effectively add Pluto back to our teachable solar system. I love the idea of bringing Pluto back into the list of planets, but it seems like the changes to our planetary classification system would also add several other planets to our solar system. Three of the largest “trans-Neptunian objects” aside from Pluto are Eris, Haumea, and Makemake, these celestial bodies are just a few of what may become the newest planets in our solar system. I will be eagerly following these planetary developments, hopefully we end up with a few new planets. I will start working on a mnemonic for the poor children who will soon be forced to memorize this new list of 17 or more planets in our solar system.
