Satellites... one of those is the Moon (Natural) which un the late 1940's and early 1950's became the first satellite transponder...
Man-made satellites orbits the Earth for the purpose of relaying messages, info and communication that serves as a basic tool for Broadcasting, Communication etc ^^, some of which are the Telstar, Agila 2 (of the Philippines) other are as follows:
a) Score - a 150 pound conical-shaped projectory. It is the first artificial used for relaying terrestrial communication.
b) Early Bird I - the first Intelsat (International Telecommunication Satellite organization) satellite. It provided over 480 voice channels.
c) Echo - a 100-ft diameter plastic balloon with an aluminum coating. The first transatlantic transmission using the satellite transponder was accomplished using Echo.
Space Junks - may be described as pieces of materials discarded from launched crafts or this may be other junks coming from scrapted or un used/obsolete satellites...
Nowadays in the advancement of technology we are now able to build space stations where different astronauts, cosmonauts and other great people can stay observed, monitor and study the Earth and the cosmos on another pint of view ^^,
Who knows in the coming years another technological advancement can add on our achievement and will orbit the Earth ^^,

Hi Shelly, Pieces of things from space orbiting earth. The moon and sun, and maybe a little alien in his space ship orbiting around the earth.LOL. This is all natural. Space stations in space orbiting the earth,and satellites watching the weather and anything that is not surposed to be there. These are man made. A Friend.

The moon, of course, and all kinds of space junk from satellite mishaps.
Space junk is a serious problem because it travels at several miles per second and can damage working satellites, shuttles, telescopes and space stations. The chances of collisions are increasing all the time, and it's predicted that some day there will be so much of it that launching any more humans into space will be too dangerous to attempt, and satellites will have to be regularly replaced as they are smashed by debris - which will create more debris.

The Moon and the Artificial Satellites or Spacecraft like Hubble Telescope, Space Stations, Communication Satellites, etc...

The moon is the biggest object so far. Theres also over 2,000 satelites for communications and such. Theres plenty of space junk from humans ( jetisioned parts from space launches and scraps) Then theres all the gas of our atmosphere and millions of tiny particles of space dust. We even orbit the earth, we jsut orbit so close we get stuck to it. And dont forget the occasional alien space craft. :D

The moon, the space station, many pieces of space garbage, and tons of satellites for phones, music and television.
