Moon is the only natural satellite of Earth.
As per the latest estimates, the total number of artificial satellites orbiting the Earth today is around 6,000. Of these, about 3,000 are not operational having lived out their useful life and are part of the space debris.
The shape of the Earth approximates an oblate spheroid, a sphere flattened along the axis from pole to pole such that there is a bulge around the equator.
