Pluto has not cleared its orbital path of debris.
Pluto started being called a dwarf planet in 2006 when the International Astronomical Union (IAU) redefined the definition of a planet. According to the new definition, a planet must clear its orbit of other debris, and Pluto does not meet this criterion. Hence, it was classified as a dwarf planet instead.
Pluto is a dwarf planet and trans-neptunian object. Crossing orbits with Neptune stops Pluto being a planet.
Pluto is not being replaced, it is simply no longer regarded as a proper planet.
Pluto isn't a moon, it orbits the sun, but it is a dwarf planet
Pluto was reclassified as a dwarf planet in 2006, after being known as a major planet for 76 years.
Pluto was founded by ancient Greek astronomers thousands of years ago. So I'll go with Pluto the planet, despite it now being a dwarf planet.
Pluto is not a star. It recently got renamed from being a "Planet" and is now called a "Dwarf Planet."
Pluto has many features on it. One bieing highlands. Another being maria. And another being craters. those are some features on pluto, they are pretty much the same as our moons! :)
its a dwarf star
The discovery of other similar objects to Pluto in more recent years has meant that astronomers either had to keep adding planets to the list, or we had to redefine what a planet actually was. In 2006, a new definition for a planet was established. It had to be approximately round, it had to orbit the sun and it had to have cleared its neighbourhood of all other objects - so that at that distance from the sun, there were no other sizable bodies. Pluto is not large enough to have done the latter, while all other remaining planets have, so it was downgraded to a dwarf planet. There are now eight planets recognised and five Dawrf planets, of which Pluto is one.
Pluto was recently stripped of the honour of being a planet
Pluto is no longer classified as a planet due to objects larger then pluto being discovered in the Kuiper Belt.
