(CNN)Way out beyond Mars, but before you get to Jupiter, is a planet. You read that right. There's a planet between Mars and Jupiter. You may not have heard of it, but it was discovered in 1801 -- 129 years before Pluto. It originally was called a planet, then later an asteroid and now it's called a dwarf planet. Its name is Ceres (pronounced like series) and you'll likely be hearing a lot more about it in the coming weeks. Ceres is one of five named dwarf planets recognized by NASA and the International Astronomical Union (IAU). The other four are Eris, Pluto, Makemake and Haumea.
