politics to seriously challenge the Republic (unlike the Mandalorians). This official galactic astrography was later re-confirmed for the first time in on-screen, live-action dialogue in The Mandalorian. In the second season's fourth episode, "The Siege", a classroom is briefly shown on a planet in the Outer Rim, in which a lesson on galactic astrography is being taught by a protocol droid. The teacher not only lists off each of these major regions from the Visual Dictionary, but lists them in the exact same order, from the Outer Rim to the Core: "Who can name one of the five major trade routes in the galaxy? The Hydian Way [runs] from the Outer Rim to as far away as the Core Worlds. However, there are several other regions within our galaxy. They are the Mid Rim, the Expansion Region, the Inner Rim, the Colonies, the Core, and the Deep Core." Star Wars canon planets and moons The following list names prominent planets and moons from the Star Wars films or other canon media. Star Wars Legends planets and moons These are planets with multiple appearances in the Star Wars Expanded Universe, now rebranded as Star Wars Legends. The accompanying works were declared non-canon by Lucasfilm in April 2014, following its acquisition by The Walt Disney Company in October 2012. Similarities to real-world planets The discovery of exoplanets in the real-world universe gained pace in the early 21st century. In 2015, the US space agency NASA published an article which stated that many of the newly discovered astronomical bodies possessed scientifically confirmed properties that are similar to planets in the fictional Star Wars universe. Kepler-452b, a rocky super-Earth-type planet, is said to be similar to the Star Wars planet Coruscant. Likewise, the planets Kepler-16b and Kepler-453b, planets discovered orbitting binary stars probably resemble the desert world Tatooine. The hot, molten worlds of Kepler-10b and Kepler-78b are comparable to the volcanic planet Mustafar. OGLE-2005-BLG-390Lb, a cold, remote exoplanet, is like the ice planet Hoth. Kepler-22b, thought by scientists to be an ocean planet, is compared to the planet Kamino. According to NASA, there are also similarities to Alderaan and Endor in the real-world universe. Solar System Two non-canonical works also feature the real-life Solar System's planets. Monsters and Aliens from George Lucas (1993) contains a feature, presented as a clip from a gossip column, in which a pair of Duros are abducted by humans
