Earth is the only Planet that:

A) Matters

D) That we can get to

Human Planet

there are nine( 9 ) planets in our solar system.

1 Mercury

2 venus

3 earth

4 Mars

5 Jupiter

6 Saturn

7 uranus

8 neptune

9 pluto

Although there are 9 planets creatures live only on 1 planet that is the earth

there are plenty of other planets but not in our solar system!

in our there are only 9

Ok Guys the universe is ever expanding I mean it never ends earth is not the only planet in the universe that keeps getting bigger and bigger and according to the Theory of Galaxies and the universe there about over 500 billion galaxies in the universe and its still counting and our galaxy is the milky way is only 1 galaxy and our solar system that holds only 8 planets (used to be 9 but they disproved that) is about 1/1000000000000000000000000000000000000 of a galaxy about the size of this period [.] compared to the whole earth so yeah if all that adds up there is roughly more a then a googol 10squared to the 100th) planets. So no Earth is not the only planet.

Earth isn't the only planet

There are 9 planets including Earth

Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune, and Pluto

Earth is DEFINATELY NOT THE ONLY PLANET there are a whole lot of other planets out there ever heard of Mars? Mercury? Venus? Neptune? Uranus? Saturn? The Milky Way? Space? The Galaxy? Star Wars????

Are you for real right now?

Um..there's seven other planets out there besides Earth (eight if you include Pluto) and scientists also believe there are other universes so there could even be more planets than what's in our solar system.

Other planets in our solar system: Mercury, Venus, Mars, Jupiter, Saturn, Uranus, and Neptune.

Sorry but there are 8 planets in the solar system.

Before there were 9 planets but Scientist's have conducted research that the 9th planet (Pluto) is a "Dwarf Planet".

A Dwarf Planet is a celestial body orbiting the Sun that is massive enough to be rounded by its own gravity but has not cleared its neighboring region of planetesimals and is not a satellite.

If you don't get it then I recommend asking your Science Teacher. They will say it more briefly and easier to understand.

I hope this answer will help you in this problem of yours.

There are 8: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Pluto was a planet, but they removed it from the list.

Earth is the only planet in which humans live on.

Yes Earth is the only planet. In the great expanse that is 'space', we are definitely on the only planet.

Good thinking but no it's the Fourth planet There's 8 planets.
