1). The orbit is an ellipse, with the center of the earth at one focus. Every point on the orbit lies in the same plane. 2). The satellite's speed is not constant. The speed is highest when the satellite is closest to the earth, and lowest when it is farthest from the earth. The line from the center of the earth to the satellite sweeps out equal areas in equal time intervals. 3). There are an infinite number of orbits possible, with different sizes and different eccentricities. If any two orbits are compared, the ratio of the squares of their periods of revolution is equal to the ratio of the cubes of the semi-major axes of their ellipses. For convenience, this description referred to an artificial satellite in orbit around the earth. But these statements are just Kepler's Laws, and they apply equally to ANY satellite ... natural or artificial ... in orbit around ANYTHING that's much more massive than the satellite ... the earth, the moon, Jupiter, the sun, or the center of the galaxy.
An artificial satellite.
First was sputnik, but anything from the Direct TV and XM radio satellites and telecommunication, GPS to the International Space Station are artificial satellites in Earth Orbit. There are artificial satellites currently in orbit around other planets as well.
The International Space Station was first started being built in 1998. It is the largest artificial orbit in space and sometimes at the right time can be seen by the naked eye.
The first launch that successfully placed an artificial satellite in earth orbit was conducted by the USSR (Soviet Union) in October, 1957. That artificial satellite was known as Sputnik I.
Sputnik was launched into a low-Earth orbit. Sputnik was launched By the Soviet Union. It was the first artificial satellite to orbit Earth. it weighed about 98 pounds and took 90 minutes to orbit earth. when Sputnik was launched the Space Race began.

the gravitational force of earth keeps the satellite(better write artificial satellite)in orbit.
Most artificial satellites are carried to the orbit multistage rockets or space shuttles. They get energy from the sun and also have nuclear reactors. How they operate depends on what they are designed to do.
Many ships have gone into space. Sputnik 1 was the first artificial satellite to orbit the earth in 1957. You will need to be more specific if you mean a particular date.

anything that man put into orbit around the earth. Examples are communication satellites and the international space station.
Currently any satellite must be launched on a rocket to reach space, though ideas for non-rocket launch exist.

Very few unmanned artificial satellites or space probes are ever recovered. They are either slowed in orbit by means of a retro-rocket, or else simply left for their orbit to decay naturally, and they are annihilated as they burn up upon re-entry into the dense lower atmosphere. Sputnik I, the first artificial satellite, burned up during re-entry after about 3 months in orbit.
"Sputnik I" was the first artificial satellite placed into Earth orbit. It was launched by the Soviet Union (USSR) on October 4, 1957.
