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.
What else can I help you with?
What year did a satellite go into orbit around venus?
In 2005 a satellite went into orbit around Venus.
What is a geostation satellite?
Geostationary satellites orbit high above the surface of the earth at about 35,000km, directly above the equator. The take the same time to complete one orbit as the earths surface as it rotates meaning it is always above the same point on earth. They are used for TV and telephone signals as well as weather imagery, among other things. A satellites period, the time it takes it to go around the earth, is determined, in part, by its altitude. The further away it is then the longer it will take. You can calculate an altitude where it will take just one day to make an orbit. If this is done then though the satellite orbits the earth it appears to be stationary above one point of the earth. This orbit must be above, or very near to, the equator. For the earth this altitude is approximately 36,000 km (22,000 miles)
Why are satellite orbits depicted as sine-wave shapes?
The sine wave represents 360 degrees or a full circle. As the satellite revolves 360 degrees around the earth in its orbit this is how it is represented on a flat surface.
In what type of orbit does a satellite follow the direction of the earths rotation seeming to hover over one spot on the equator?
Synchronous orbitThis is where an orbiting body (moon) has a period equal to the average rotational period of the body being orbited (planet), and in the same direction of rotation as that body.
What is non-geostationary satellite?
A geostationary orbit is an orbit of the Earth that is circular, over the equator, and at the right distance to have a period of 24 hours. A satellite in such an orbit appears to hang motionless, always at the same point in the sky Anything else is a non-geostationary orbit. A satellite in one of those appears to move in the sky, so that if you want to communicate with it, you need a movable dish.
Where is a satellite when it stays at the same point above earths surface?
A satellite is considered to be in geostationary orbit when it stays in a fixed position above a specific point on Earth's surface. It orbits at the same rate as the Earth's rotation, which allows it to remain stationary relative to the ground below. Geostationary satellites are commonly used for communication and weather monitoring purposes.
An orbit in which a satellite travels at the same speed as the earths rotational speed is called?
That's a 'geosynchronous' orbit. If it also happens to be over the equator, so that the satellite appears to stay at the same point in the sky, then it's a 'geostationary' orbit.
What are the names of some satellites currently in earths orbit?
Sutnick was the very first Satellite that was put into orbit.=)
Is the earth's natural satellite the sun?
no, the moon is the Earths natural satellite, the moon is in orbit around the Earth. The whole Earth/Moon system is then in orbit around the sun.
How does a weather satellite get into orbit?
It's lifted into space by a big rocket.
What is a satellite and why is the moon referred to as the earths satellite?
satellites are things that orbit other things in space, for example the moon orbits the earth and is therefore the earth's satellite
How does the direction of motion of a satellite in circular orbit compare with the curve of earth's surface?
The direction of motion of a satellite in a circular orbit is perpendicular to the curved surface of the Earth. This means that the satellite moves parallel to the surface at a constant distance rather than following the curve of the Earth.
What is the significance of the geo orbit radius in relation to satellite communication?
The geo orbit radius is significant in satellite communication because it determines the satellite's position relative to the Earth. Satellites in geostationary orbit, which have a radius of about 22,236 miles, appear stationary from the Earth's surface. This allows for continuous communication with fixed ground stations, making them ideal for services like television broadcasting and weather monitoring.
Why is a polar orbit useful for surveying purposes?
it carries the the satellite over the earths north and south poles
What is the altitude of the lowest flying satellite?
the lowest flying satilite is DAN 100kl above the earths surface
What type of orbit does a weather satellite have and why?
The polar orbit so that it can measure cold and hot points around the entire earth :)
Is the moon a place or thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.
