look at the shape of it
over a thousand artificial satellites. the first artificial satellite was sputnik. the only natural satellite earth has is the moon
for the circular motion of a satellite a centripetal force is requid. these force is supplied by the gravitional force between the earth and satellite this is trueall objects in the satellite is zero ie, the object in a satellite feel weightlessness
artificial. it is the largest artificial satellite that has ever orbited earth
Satellite
The only NATURAL satellite of the Earth is the Moon. There are more than a thousand artificial satellites of the Earth.
-- An artificial satellite can be operated and observed in a 'polar' orbit, in which it eventually overpasses every point on Earth, or in any other desired orbit. The moon's orbit is inclined about 5 degrees to the plane of the ecliptic, which is a nice orbit, but that's where it stays. So there's a full 62-degree 'cap' around both the north and south poles, where the moon can never be overhead. -- An artificial satellite can be operated and observed in an orbit with any desired eccentricity, and the eccentricity can be controlled and modified at will. The moon's orbit has a mean eccentricity of only 0.055, and the orbit has many irregularities and perturbations, which have been studied for many years. -- For each revolution of the Moon, the Earth rotates inside the Moon's orbit 27.32 times. The orbit of an artificial satellite can be adjusted so that for each revolution, the Earth rotates within the satellite's orbit any number of times, from zero and on up. -- Since the mass of any artificial satellite is so much less than the mass of the moon, and since most artificial satellites spend most of their time nearer to Earth than the Moon is, small local irregularities in the shape of the Earth's gravitational field have a much greater influence on the orbits of the artificial ones.
The Moon is the only natural satellite of the Earth, but the Earth also has several thousand artificial satellites in orbit.
Presently it is the ISS
There are those who claim that the Earth's moon is an artificial satellite.
The only sizable natural satellite in orbit around the Earth is the Moon. The first artificial satellite was "Sputnik" launched by the Soviet Union in 1957, since then the number of artificial satellites around the earth is numbered in the thousands.
Earth has one natural satellite, the moon, and numerous artificial satellites, the first of which was called Sputnik, which can deservedly be called Earth's second satellite.
