1, The moon
One natural. Many hundreds artificial
There are weather sattellites that orbit the Earth that can detect reflected radiation, emitted radiation, or radiation reflected only by water vapour as well as satellites that emit microwave radiation to detect the clouds or precipitation.
I am not sure if this is correct but I believe we don't need sattallites for computers but we do need them for the Internet
We live on the earth. The earth has many natural resources. On earth, we experience a wide range of temperatures.
The Earth only has one main natural sattelite, and that is the moon. There could be many little rocks orbiting the Earth, but who knows!
just one: the moon
the earth can never be pollution free as there are natural incidents, such as methane from animals and their waste or co2 from natural fires, there are many other natural disasters that can cause all sorts of pollution to the planet, and with humans on earth the chances of no pollution is at nil
The only natural object we know of that does that is the earth's moon.
