For many years, Pluto was considered the ninth planet of our solar system, alongside the likes of Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.

After the discovery of Neptune, it was seen as a confirmation of celestial mechanics in astronomy. It was noticed that Uranus’ orbit was being affected by another planet, which led to Percival Lowell’s search for Pluto, initially called Planet X. Clyde Tombaugh took over the search after Lowell’s death and successfully found Pluto.

Until 2006, Pluto was considered one of the solar system’s nine planets, named after the Roman deity of the Underworld. However, it was later reclassified as a “dwarf” planet by the International Astronomical Union due to not meeting the criteria for a full-sized planet and being smaller than Earth. The first two letters of “Pluto” are believed to be a tribute to Percival Lowell, whose belief in the existence of additional planets beyond Neptune contributed to its discovery.
