No planets like Earth of any size have been discovered.
For a planet the size of the Moon to have Earth like characteristics, it would have to have a much larger iron core in order to hold on to an atmosphere.
Yes Earths Moon is a rocky planet
earths moon
Pluto is the dwarf planet that is smaller than the Earth's moon.
It's true, the moon is smaller than the Earth.
the moon creats earths tides! It also effects the planet by stabilizing the rotation of earth!
In size and mass it is enormous compared to it's parent planet - The Earth.
the moon
The moon was created when another planet slammed into Earth - the Earths gravity captured the particles and the formed to become our moon.
The sun does not orbit around the moon. The earth orbits the sun and the earths moon (every planet has 1 or more moons) orbits earth.
They are round in shape, also they have crater's. However the moon has no water or life, but Earth does. Earth is a planet and the moon is not.Also how the moon is different is it is 1/6th of Earths gravitational pull.
the moon orbits the earth and one definition of a satellite is "a natural body that revolves around a planet"
the earth;s companion is the moon no doubt
