5. The Planet Earth To be called a planet the object must orbit the Sun.
It must be big enough for gravity to squash it into a round ball,
It must have cleared other objects out of the way in its orbital neighborhood.
To clear an orbit, a planet must be big enough to pull neighboring objects into the planet itself or sling-shot them around the planet and shoot them off into outer space

6. The Planet Earth
The Earth is unlike every other planet in the Solar System in a number of different ways.
It is the only planet that has an atmosphere containing 21 percent oxygen.
It is the only planet that has liquid water on its surface.
It is the only planet in the solar system that has life.
The Earth is the only inner planet (Mercury, Venus, Earth and Mars) to have one large satellite, the Moon.  Mars has two very tiny moons.  Mercury and Venus have none.

7. Pluto ---The Dwarf Planet
Is a small planet but lacking certain technical criteria that are required for it to be classed as such.
Pluto was discovered by use of a telescope in the 1930’s. 
The first eight planets orbit the Sun in a path which they have cleared of other objects.  Pluto, however, orbits the sun in a zone which is full of other objects that often pass between Pluto and the Sun.
The first eight planets orbit the Sun while keeping the same distance from the Sun.  The Earth is always 93 million miles, one Astronomical Unit, from the Sun.  Pluto, however, orbits in an ellipse, an oval shape which means its distance from the Sun varies.
