What is the main reason why Pluto is no longer a planet?
- For me, my understanding on Pluto was excluded from the list of planets because it did not meet the necessary criteria to be officially classified as a planet. Also Pluto's inability to orbit independently implies that its trajectory is influenced by other celestial bodies, making it deviate from the typical characteristics of a planet.
The International Astronomical Union (IAU) verified that Pluto is not capable of conducting its own orbit.
Pluto needs to exhibit three key traits in order to be known as planet:
1. Pluto is expected to maintain a consistent orbit around the Sun.
2. Pluto should have exact and sufficient gravity.
3. Pluto is required to clear its vicinity of other objects as it orbits around the Sun.
Therefore, Pluto was reclassified as a dwarf planet because it does not meet the requirement of clearing its orbit by consuming or ejecting nearby celestial bodies.
What is Dwarf planets?
- Planets are rounded celestial objects that lack their own light and revolve around a star. Dwarf planets are a specific classification for celestial bodies that are comparatively smaller in size compared to other planets.
The Pluto is no longer a planet as it not cleared it's path yet.
The three basic reasons for a celestial body to be a planet are:
1. The planet must orbit or revolve around the sun.
2. It has to be round or sphere-shaped.
3. It must sweep out neighboring regions on the planets around it.
Pluto obeys the first two rules, but it does not follow the third. According to this rule, a planet must have some gravitational fieldof its own so that other celestial objects can follow. These objects may later become the moons of a particular planet and keep revolving around a planet. But for Pluto, many asteroids are still revolving around it, and these are not its moons.
Pluto has very little acceleration due to gravity. Hence, it cannot make any other celestial object revolve around it and become its moon. Due to this reason, Pluto is no longer a planet. Further, Pluto keeps changing its behavior while orbiting the Sun.
