Technically, the Earth and any satellite both circle their mutual center of mass. Just like the balancing of an adult and a child on a see-saw, since the earth's mass is several times the mass of the satellite, their common center of mass is closer to the earth's center than it is to the satellite. Even in the case of the moon, the pair's common center of mass is inside the earth. In the case of any man-made artificial satellite, the mass ratio is several gazillion, and the common center of mass can't be more than a hair's breadth from the earth's center. So for any satellite, including the moon, it looks exactly as if the satellite is circling the earth.
Anything that revolves around something is a satellite.
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon
moon is to satellite as earth is to planet
The only natural satellite of the Earth is - the moon.
Satellite pictures of Earth are taken by a camera mounted on a satellite in orbit, high above Earth's atmosphere. They are transmitted wirelessly over satellite signals, much like satellite TV.
A satellite small enough to be treated as a point particle. Can earth's gravity exert a torque on a satellite about the earth's center? Torque causes an object to rotate around a specific point. Torque = force * perpendicular distance and Torque = moment of Inertia * angular acceleration. When a satellite is launched, it is forced up to a specific distance from the earth's center and accelerated to a specific velocity parallel to the surface of the earth. The satellite continues moving in circular orbit. The force which causes the satellite to move in a circular path is the gravitational force caused by the mass of the earth, mass of the satellite, and distance from the center of mass of the earth to the center of mass of the satellite. This force causes the direction of the velocity to rotate so it is always tangent to the circle. This force produces the torque which makes causes the satellite to rotate so the direction of its velocity is always perpendicular to the direction of the gravitational force.

What is an object sent into space to circle earthA satellite ?
Russia
because it is pushed by aliens around the earth

Russia (U.S.S.R.) had the sputnik
About an hour.
From the question, I'm guessing that when the questioner reads the term "polar orbit", he's picturing the satellite doing a little tiny circle in the sky over the North Pole. This is not an accurate understanding of the term. Remember that the center of the orbit of an artificial satellite has to be at the center of the earth. A 'polar orbit' is an orbit that covers both poles. If you picture the globe of the earth, the satellite's orbit is a circle standing up, with the satellite traveling up and down, passing over both poles in each complete revolution of the earth. As the earth rotates, every point on earth passes under the orbit, and sooner or later, every point on earth will be visible from the satellite.
A satellite can be natural or artificial. An artificial satellite is placed in orbit around the earth, moon, or another planet in order to collect information or for communication. A natural satellite is a celestial body orbiting the earth or another planet.
It certainly gets pulled toward the Earth. Without the pull of gravity, the satellite would continue moving in a straight line, instead of going around the Earth in a circle or ellipse.
Yes, the moon is a natural satellite of the Earth.
