Pluto was finally discovered in 1930 by Clyde Tombaugh at the Lowell Observatory, based on predictions by Lowell and other astronomers. Pluto got its name from 11-year-old Venetia Burney of Oxford, England, who suggested to her grandfather that the new world get its name from the Roman god of the underworld.

Just so, why Pluto is not considered a planet anymore?
The International Astronomical Union (IAU) downgraded the status of Pluto to that of a dwarf planet because it did not meet the three criteria the IAU uses to define a full-sized planet. Essentially Pluto meets all the criteria except one—it “has not cleared its neighboring region of other objects.”
Likewise, should Pluto still be considered a planet? In 2005, Eris, a dwarf planet in the scattered disc which is 27% more massive than Pluto, was discovered. This led the International Astronomical Union (IAU) to define the term "planet" formally in 2006, during their 26th General Assembly. That definition excluded Pluto and reclassified it as a dwarf planet.
Hereof, why is Pluto considered a dwarf planet?
Because it has not cleared the neighborhood around its orbit, Pluto is considered a dwarf planet. It orbits in a disc-like zone beyond the orbit of Neptune called the Kuiper belt, a distant region populated with frozen bodies left over from the solar system's formation.
Is Pluto a planet again 2019?
NASA Administrator Says Pluto Is Still a Planet, And Things Are Getting Heated. Saturday 24 August 2019 marked a vexing anniversary for planetary scientists.
Related Question AnswersWhat is Pluto called now?

Composed predominantly of hydrogen and helium, the massive Jupiter is much like a tiny star. But despite the fact that it is the largest planet in the solar system, the gas giant just doesn't have the mass needed to push it into stellar status. When scientists call Jupiter a gas giant, they aren't exaggerating.Is the sun a planet?

Pluto was discovered in 1930 by Clyde Tombaugh. Astronomers noticed that the orbits of Neptune and Uranus were being affected by the gravity of an unknown object in the Solar System. Clyde Tombaugh carefully studied images of the night sky, and after a lot of hard work he finally discovered Pluto.Why is solar system flat?
The solar system is indeed pretty much a flat sheet, with the major planets all orbiting in a very thin plane surrounding the Sun. Part of the reason we don't tend to send spacecraft in the 'up' direction, out of this thin plane, is simply that there's not very much there!Does Pluto support life?
For there could be life beneath Pluto, and there could be many more ocean worlds in the Milky Way than previously thought, according to new research that theorizes that a possibly life-supporting subsurface ocean could exist on the distant icy dwarf planet Pluto.Why is Pluto important?
Pluto is a planet of extremes because its orbit is very severe. Pluto takes 248 years to circle to the sun-- moving dramatically closer to and farther from the Sun. This causes temperatures to fluctuate greatly.Can humans live on Pluto?
It is only half as wide as the United States. Pluto is smaller than Earth's moon. This dwarf planet takes 248 Earth years to go around the sun. If you lived on Pluto, you would have to wait 248 Earth years to celebrate your first birthday.Does Pluto have seasons?
Pluto's seasons. With an orbital eccentricity of 0.24, Pluto is almost twice as far from the Sun at aphelion than at perihelion. Its seasons are aligned with this elliptical orbit such that perihelion occurs at the transition from northern winter to spring.How did Pluto get its name?
Pluto was finally discovered in 1930 by Clyde Tombaugh at the Lowell Observatory, based on predictions by Lowell and other astronomers. Pluto got its name from 11-year-old Venetia Burney of Oxford, England, who suggested to her grandfather that the new world get its name from the Roman god of the underworld.Is Pluto a gas planet?
So inconspicuous that it was not discovered until 1930, Pluto is not a gas giant planet like all the others in the outer solar system. Instead it is a small, rocky world about the size of Earth's Moon.What planets are in the Milky Way?
