The numbers vary among estimates, but there are between 2100 to 2200 functioning artificial satellites in Earth orbit. Russia has the greatest number at around 1324. The U.S. is second with 658 satellites in orbit.
One natural satellite, the moon, but there are hundreds of artificial, or 'Man-Made' satellites including communications, military and many more. One of the most famous artificial satellites is the International Space Station, or the ISS.
People call this debris "space junk". "Space junk" orbits at a speed of roughly 7.5 kilometers/second. That is close to 17,000 miles/hour! Think of the damage even a small speck of paint could do to the space shuttle if impact occurred at such high speeds ! Another definition of satellite is a manufactured vehicle intended to orbit the Earth. This definition makes our count much less because it includes only spacecraft and not debris that orbits the Earth. The Goddard Space Flight Center's lists 2,271 sate llites currently in orbit. Russia has the most satellites currently in orbit, with 1,324 satellites, followed by the U.S. with 658.
The weather satellites that you see the pictures from on the 9:00 news are
in geostationary orbits. They're over the equator, and orbit the Earth exactly
once a day.
None. Satellites can't stay up if they're in the atmosphere. They have to be above it,
where there's practically no air at all. If a satellite drops low enough to be in air, it
slows down and falls out of orbit almost immediately.
One natural and thousands of artificial ones. Do we count the pieces of satellites, and the expended rocket motors that launched them, and the things that fell off of them? Tens of thousands.

Earth has one natural satellite, the Moon.
NASA is tracking more than 12,000 pieces of debris and satellites that are orbiting Earth currently. Every so often, two of them collide.
There is 1
It's virtually impossible to tell exactly how many satellites orbit the sun, for there are millions of billions of trillions of objects orbiting the sun in our solar system, including planets, asteroids, man-made satellites, etc. There are way too many to count, so in general, there are many objects orbiting the sun, and the only answer I can say is "many," and give some examples like told above.

Earth has a variety of satellites as explained below. (See related links for sources.)
Natural Satellites:
Earth has one natural satellite. The Moon.
Quasi Satellites:
Quasi-satellites accompany Earth as it orbits the Sun but while located near Earth and affected by Earth's gravitational pull, they actually orbit the Sun and not earth. Their orbits are unstable they appear and disappear over thousands of years. There are at least five such quasi-satellites, including Cruithne which was discovered in 1986 and has been called "Earth's second moon" though it is only 5 kilometers in size and does not actually orbit Earth. The designation of quasi-satellites is ambiguous and there may be more that have not been observed, so there is no fixed number.
In 2010 it was discovered that Earth posses at least one Trojan asteroid that precedes Earth as it orbits the Sun. This asteroid exists in a stable gravitational fixed point known as a Lagrangian point. Trojan satellites had been previously seen associated with other planets in the solar system. It is expected that more will be discovered.
Artificial Satellites:
As of April, 2013, there are 3707 artificial satellites in orbit around Earth.
Debris:
This does not include various sorts of debris which remain in orbit, intentionally or not, from previous launches. There are at least 13 144 such objects, not including an uncountable number of small pieces that are strewn about as a result of intentionally discarded trash or accidents or collisions.
The Goddard Space Flight center tracks something like about 2,300 satellites in orbit about earth, other than the one natural satellite (the Moon). The Russians have over 1,300 birds aloft, and the US has between 600 and 700 of them up.
Modern uses are to merely name different stars and to locate them in the sky.
Direct to home (DTH) television is a wireless system for delivering television programs directly to the viewer's house. In DTH television, the broadcast signals are transmitted from satellites orbiting the Earth to the viewer's house. Each satellite is located approximately 35,700 km above the Earth in geosynchronous orbit. These satellites receive the signals from thebroadcast stations located on Earth and rebroadcast them to the Earth The Overall System Early satellite TV viewers were explorers of sorts. They used their expensive dishes to discover unique programming that wasn't necessarily intended for mass audiences. The dish and receiving equipment gave viewers the tools to pick up foreign stations, live feeds between different broadcast stations, NASA activities and a lot of other stuff transmitted using satellites. Some satellite owners still seek out this sort of programming on their own, but today, most Direct to home TV customers get their programming through a direct broadcast satellite (DBS) provider, such as DirecTV or the Dish Network. The provider selects programs and broadcasts them to subscribers as a set package. Basically, the provider's goal is to bring dozens or even hundreds of channels to your television in a form that approximates the competition, cable TV. Unlike earlier programming, the provider's broadcast is completely digital, which means it has much better picture and sound quality. Early satellite television was broadcast in C-band radio -- radio in the 3.4-gigahertz (GHz) to 7-GHz frequency range. Digital broadcast satellite transmits programming in the Ku frequency range (12 GHz to 14 GHz ).
Not usually. The car would have to be planted in the ground or the satellites camera would have to be at a shallow angle to earth. Yes and there will be to much atmosphere in the way that will distort the image, the best resolution by Google earth is 15 cm/pixel I really don't think so, I think the best resolution a satellite can reach is about 60mm per pixel and one letter or number is smaller than 60 mm it will only show up as a black or white spot. but this answer is open for debate
Some inventions that immediately come to mind are airplanes, mass produced automobiles, radio, television, antibiotics, polio vaccines, computers, digital sound reproduction, transmission, and recording, artificial earth satellites, synthetic fibers ( e.g. nylon, etc), plastic, nuclear power, submarines , motion pictures, electric musical instruments and bikinis.
There is no current US space station. The last US space station was called SkyLab - but it entered Earth's atmosphere in 1979. The US (through NASA) currently uses the International Space Station or ISS.
The different artificial satellites launched are Low Earth Orbiting Satellites for Remote sensing, Medium Earth Orbiting Satellites like GPS , Geo Stationary Orbiting Satellites for Communication and Molnia Satellites again for Communication. These are the different artificial Satellite orbiting the Planet Earth.
Anything orbiting the earth is a satellite including the glove that floated out of the Gemini spacecraft. The obvious satellites include communication and spy. Gps also uses satellites.
There are over 1000 operational satellites orbiting the Earth, and probably 10,000 pieces of "space junk" also orbiting the Earth.
the termosphere
Yes there are enough gravitational forces to keep the satellites orbiting earth.
Old satellites orbiting near the Earth eventually fall back into the atmosphere and burn. Satellites orbiting farther away stay in orbit indefinitely.
exosphere
There are a great number of satellites currently orbiting the Earth, and they are ALL important; at least, important enough to SOMEBODY to spend millions of dollars to launch each one.Depending on your interests, the "most important" satellites are probably the weather forecasting satellites, followed by the communications and GPS satellites.

A space station and many satellites.
