Pluto: Everything you need to know about the dwarf planet Space: Emily Safron, instructor of astronomy, talked about Pluto, and went into detail about why it is now considered a dwarf planet in our solar system. “Even one of its own moons, Charon, is about half of Pluto’s size. So, rather than being the runt of the planet group, Pluto is now the ‘king’ of the dwarf planet group!” Saffron said. |
