Of all the moons in the solar system ours is the 5 th largest.
The moon is not a planet but a satellite of the earth.
At some point in the next hundred thousand years or so that will.
The rugged lunar terrain is responsible for the dark and light spots observable from earth.
For a short time our planet was orbited by a second tiny natural satellite.
The surface of the moon is made up of silica alumina lime magnesia titanium and sodium oxide and all this are minerals that are present on earth which adds.
As far as the composition of the moon goes it is made up mostly of an iron rich core a fluid outer core made of liquid iron that is covered by solid mantle and crust.
The moon is an astronomical body orbiting earth and is the planet s only natural satellite it is the fifth largest satellite in the solar system and by far the largest among planetary satellites relative to the size of the planet that it orbits.
How could we know the moon is not a natural planet.
Earth was not considered a planet but rather was thought to be the central object around which all the other celestial objects orbited.
The moon is a little more than one quarter of the size of earth another bizarre characteristic compared to any other natural satellite in our cosmic region.
It is in the strangest position imaginable relative to the sun and the earth and it behaves in the most incredible way every month.
This appears to be a quite ludicrous statement.
The answer is that we know because it is too big yet too light in mass.
The ancient greeks counted the earth s moon and sun as planets along with mercury venus mars jupiter and saturn.
The moon is not a natural planet.
It is 240 250 miles away from the surface of the earth and the closest celestial object.
The moon is the earth s only natural satellite and the clearest object in the night sky.
Besides it does not have the size or the gravitational force of a planet and therefore the moon is simply a satellite object that is neither a star nor a planet.
