While playing Cookie Jam, you may come across the clue “Is it a dwarf planet or not?”. This clue points to one of the most famous and debated objects in our solar system.
For many years, students around the world learned that Pluto was the ninth planet from the Sun. It was discovered in 1930 and quickly became part of the standard list of planets. However, as scientific understanding improved, astronomers began to question whether it truly fit the definition of a planet.
In 2006, the International Astronomical Union introduced a new set of rules for classifying planets. According to these rules, a planet must meet three conditions: it must orbit the Sun, be round in shape due to its gravity, and clear its orbital path of other objects.
Pluto meets the first two conditions—it orbits the Sun and has a nearly spherical shape. However, it does not clear its orbit, meaning it shares its space with other objects in the Kuiper Belt. Because of this, scientists reclassified it as a dwarf planet instead of a full planet.
This decision sparked debates around the world. Many people were surprised or even disappointed because they had grown up learning Pluto as a planet. Despite the change, Pluto remains one of the most well-known and studied objects in space.
