Earth

The earth is the planet on which we all live, along with a whole lot of other organisms. Of all the planets we currently know (including those outside our own solar system), Earth is as far as we know the only one with living beings. Earth is a stone planet and is also called the 'blue planet'. The Earth also has one moon. Scientists at Wikimini calls it the spaceship earth and points out to all of us the vulnerability of the earth.
