To qualify as a planet, a body has to be approximately spherical (achieving hydrostatic equilibrium under its own gravity), it has to orbit the sun and it has to have cleared its orbit of all other objects - so that at that distance from the sun, there are no other sizable bodies. Some dwarf planets, like pluto, fulfill the first two requirements, but not the last one, this is why they are deemed dwarf planets rather than planets.

Characteristics of planets?
The IAU came up in 2006 with three definitions for a planet: # It must orbit the Sun. # It must be large enough for gravity to mould it into a nearly spherical shape. # It must have cleared the neighbourhood around its orbit. The third definition excluded Pluto as a planet.

What are three things that are being done to help fix or replenish the environmental sustainability on your planet?
Three things that can be done to help fix or replenish the environmental sustainability of your planet include recycling, replanting, and limiting the use of natural resources. By allowing the planet to rebuilt itself, humans will have a less significant impact.
Is moon a planet by science?
No. The official definition of a planet has three parts, and failure of any of the three parts means the object is not a planet. 1. The object must be round. The moon meets this part of the definition. 2. The object must orbit the sun. The moon fails this part - it orbits Earth, and Earth orbits the sun.
When was planet Pluto is called a dwarf planet?
In August of 2006, the IAU (International Astronomical Unit) declared the definition of a planet. In order to be a true planet, a planet must meet these three criteria.It must be an object which independently orbits the SunIt must have enough mass so that gravity pulls it into a roughly speroidal shapeIt must be large enough to "dominate" its orbit (ie. its mass must be much larger than anything else which crosses its orbitPluto does not meet all 3 criteria, therefore it is not a true planet, but a Dwarf Planet.

Pluto the dwarf planet?
Pluto, the dwarf planet, is the smallest planet in our solar system. In 2006 scientists confirmed that Pluto was a dwarf planet. They confirmed this because Pluto does not have a clear orbit around the sun. The things that a planet must have in order to be a planet is that it MUST have a clear orbit around a star. FUN FACT: Pluto's moon is almost as big as itself! Pluto is the coldest planet in our solar planet. Pluto is an outer planet.
