For a short time our planet was orbited by a second tiny natural satellite.
The moon is not a planet but a satellite of the earth.
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.
How could we know the moon is not a natural planet.
The moon is not a natural planet.
At some point in the next hundred thousand years or so that will.
No other planet that we re aware of has a moon that is as proportionately big as ours.
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 answer is that we know because it is too big yet too light in mass.
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.
The moon is after jupiter s satellite io the second densest satellite in the solar system among those whose densities are known.
Unless it hits the earth or moon in the process.
The rugged lunar terrain is responsible for the dark and light spots observable from earth.
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.
The moon is the earth s only natural satellite and the clearest object in the night sky.
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.
Of all the moons in the solar system ours is the 5 th largest.
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.
