Pluto's reclassification as Kuiper Belt object
- Pluto was removed from the list of major planets, causing controversy among people who felt it was being excluded from the planetary family.
- The discovery of the planet Ceres between Mars and Jupiter led to the identification of numerous small planets, eventually known as asteroids, forming the asteroid belt.
- Astronomers later found thousands of small planets similar to Pluto in the Kuiper Belt, leading to the reclassification of Pluto as part of a belt of small planets rather than a major planet.
- The Kuiper Belt, named after astronomer Gerard Kuiper, is located at the far end of the solar system, prompting scientists to differentiate Pluto from the major planets due to its association with this belt.
