There are several man made satellites that orbit the Earth. The moon is the only satellite that orbits the Earth in a counter-clockwise fashion, from west to east.
The largest satellite orbiting the Earth is the Moon.
The only natural satellite orbiting Earth is the moon.
Photos taken of Earth from an orbiting satellite
I saw a satellite orbiting around earth.
It is the moon.
By orbiting the earth about once a month.
The first successful earth-orbiting artificial satellite was launched from the USSR in October 1957. Once it had achieved orbit, its name was announced to the world as "Sputnik-1".
A satellite is not always a robotic module constructed on Earth and launched into orbit. A satellite, in fact, is any object which is orbiting another. The orbiting object is the satellite of whatever it orbits. By now you ought to be able to guess it, but if not, it is the moon.
At periapsis, that is, when it is closest to Earth in its orbit.
If the Moon is to a satellite, then Earth is to a planet. The Moon is a natural satellite orbiting Earth, just like artificial satellites orbit Earth. Similarly, planets are natural satellites orbiting stars, like Earth orbits the Sun.
