"This definition, which applies only to the Solar System, states that a planet is a body that orbits the Sun, is massive enough for its own gravity to make it round, and has "cleared its neighbourhood" of smaller objects around its orbit. Under this new definition, Pluto and the other trans-Neptunian objects do not qualify as planets."
Mercury is the SMALLEST (littlest) PLANET in our solar system, it WAS the SECOND SMALLEST PLANET PRIOR TO Pluto being demoted from a classification of Planet, to a classification of Planetoid.
The dwarf planet Pluto lost its classification as a planet in 2006.
Pluto's classification was changed from a planet to a dwarf planet in 2006 by the International Astronomical Union because it did not meet all the criteria to be considered a planet, specifically it has not cleared its orbit of other objects in its path. This reclassification was based on new understanding and definition of what constitutes a planet in our solar system.
A new classification you idiot!
Venus is a Terrestrial Planet.
Saturn is not a rocky planet.Saturn is not a glass planet. (by the way I know of no such classification as a "glass" planet).Saturn is a gas giant planet.
Earth is classified as a terrestrial planet, which means it is a rocky planet with a solid surface. It is the third planet from the Sun in our solar system and is the only known planet to support life.
Pluto is no longer classified as a planet, but rather as a dwarf planet. The celestial body still exists -- it has simply lost its previous classification status.
Pluto and if you are using this for work than I know, and I will contact and school principle ERMS
Domain is the broadest level of classification in the new system, higher than kingdom in the old classification system.
In 1930, the dwarf planet Pluto was discovered by astronomer Clyde Tombaugh. Initially classified as the ninth planet in our solar system, Pluto's discovery expanded our understanding of the outer reaches of the solar system. However, it was reclassified as a dwarf planet in 2006 by the International Astronomical Union due to new criteria for planet classification.
