What is earths oldest satellite?
Vanguard1
What satellite circles the earth exactly once a day?
The moon is the earths only natural satellite
Was Sputnik Earths first artificial satellite?
It was the first human-made satellite, (launched from Russia on Oct. 4, 1957), to orbit the Earth. A space probe leaves the orbit of Earth and goes off into distant space. Sputnik only left Earth's orbit to burn up in the upper atmosphere on Jan. 4, 1958.
What type of satellite orbits perpendicular to the earths equator?
polar satallite
Earths gravity as a percentage?
enough to keep us on it
Why can a satellite orbit above the moon at 5km and not the earth?
At 5km up the Satellite would still be in the earths atmosphere and would also be subject to gravity. Put simply it would just fall back down. Space starts at about 100km up or 62 miles. The moon also has 1/6ths of Earths gravity and at 5km up there would be little if any pull from the moon.
Why at height the artificial sateillte not pulled toward the earth?
The satellite is being pulled by the earths gravity all of the time, but the satellite also has an orbital velocity, meaning that is is travelling at high speed. These two opposing forces balance out, the 'sideways' speed of the satellite wants to take it away into space, but the gravity of the earth is always pulling it in. The satellite maintains its speed as there there are no frictional forces to slow it down in space, so it maintains an orbit.
Does a satellite in low tilt at low altitude show more of the earths surface than one in high tilt at same altitude?
Yes, a satellite in a low tilt at a low altitude will cover more of the Earth's surface due to its proximity and angle of view compared to a satellite in a high tilt at the same altitude. The lower tilt allows for a larger field of view, capturing more of the Earth's surface in a single orbit.
Is moon is place or thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.

Is it correct to say that satellites fall back to earth falling to earth because they are beyond the pull of earths gravity explain?
That is not English; that is not physics. Generally speaking, the speed of the satellite and gravity cancel each other. As the satellite slows (friction), gravity wins.
What is a common model for Einstein's theory of gravity?
Whatever goes up and remains within the influence of earths gravity must come down, or circle the earth as a satellite.
Does a satellite orbit earth free from earths gravity?
No. Gravity is responsible for all 'orbits'. If there were no other body attracting it, the orbiting object would sail off in a straight line.
What is the altitude of the lowest flying satellite?
the lowest flying satilite is DAN 100kl above the earths surface
