How is a weather satellite in polar orbit able to view Earths surface?

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 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.
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.
If a satellite orbiting just above the surface of the Earth orbits in about 1.5 hours then at about how many Earth radii from the Earth's center must a satellite orbit to have a period of 24 hours?
You can use Kepler's Third Law to calculate this.
Where is a satellite when it stays at the same point above earths surface?
That's a "geostationary" satellite. It's roughly 22,000 miles above the equator, in a circular orbit.
What are the names of some satellites currently in earths orbit?
Sutnick was the very first Satellite that was put into orbit.=)
A satellite communication system why is the geostationary orbit preferred?
A geostationary orbit will keep the satellite in one area relative to the surface
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 rocket get out of earths orbit?
surely a rocket or artificial satellite can get out with help of escape velocity....
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
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.
Why is a polar orbit useful for surveying purposes?
it carries the the satellite over the earths north and south poles
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 a moon a place or a thing?
nither it is a natural satellite held in orbit by the earths gravity. Without it we would have no tides.
