Which orbit would be best for investigating the Arctic and Antarctic?
If the satellite is in an orbit that takes it over the North and South Poles, it will eventually cover all parts of the Earth as the Earth spins beneath it. This kind of orbit is called a polar orbit.
If an orbit of a planet breaks?
The orbit of a planet is not any kind of physical object; it cannot "break". An orbit is the path that a satellite (natural or artificial) takes under the influence of gravity.
Why is moon called a satellite not a planet?
moons are satellites because technically, they orbit a planet, not the sun. it is true that it does kind of orbit the sun, but that's only because the planet it orbits is orbiting the sun.
How long does it take to orbit the earth?
That depends on the size of the revolving object's orbit away from the surface of the earth. The larger the orbit, the longer it takes for the object to complete one revolution. The SHORTEST possible time is about 86 minutes. That's the period of an orbit that's just high enough so that atmospheric drag doesn't immediately bring the object down. If the orbit is about 238,000 miles out from the earth, then the period for one revolution is about 27.3 days. There's one satellite in that kind of orbit right now.
What direction do satallites go circling the earth?
They go around and around. More artificial satellites proceed from west to east, because it takes less energy (fuel) to launch a satellite into that kind of orbit. But there's no fundamental reason why a satellite can't go in any direction you want. The only requirements are . . . -- The center of the Earth has to be in the plane of the orbit. -- If you expect it to stay up there for a while, then the satellite has to stay outside most of the Earth's atmosphere.
Geo space orbit?
It is a little strange that things in higher orbits actually travel more slowly than things in lower orbits. The Space Shuttle and the International Space Station both orbit in about 90 minutes, while the Moon - 250,000 miles away - take a whole month to orbit the earth. There is one kind of orbit that has a special name and a special purpose. A satellite that orbits at 22,300 miles high will orbit the Earth in 24 hours. You might notice that the Earth revolves around its axis in 24 hours. So a satellite at that altitude orbits the Earth at the same rate that the Earth turns, which means that the satellite is moving just as fast as the Earth does. So the satellite appears to stand still in the sky! We call this a geo-synchronous orbit. Geo, for Earth; synchronous, for "equal time". This is an especially handy orbit for things like communications satellites, which "hover" over the same spot on the equator.
Why must communication satellites travel 35000 kilometers above earths surface?
The requirement is to place the satellite in such a way that it appears motionless in the sky, as seen from the surface of the earth. This is a great advantage in satellite communication, because if the satellite appears stationary, then the dish antenna on the ground doesn't have to move to follow the satellite ... the dish can be aimed once, and can stay in the same position permanently. In order to have the satellite appear motionless, it has to follow the 24-hour rotation of the earth. The orbital period of any satellite's revolution (around a much larger body) depends only on the average orbital distance. For the earth, the period of a 238,000-mile orbit (where the moon is) is about 27 days, and the period of an orbit that averages about 22,400 miles is 24 hours. So a communications satellite in an orbit with this average distance will complete one revolution around the earth in 24 hours. Wherever it is right now, it will appear in the same exact place 24 hours from now. This is a "geosynchronous" orbit. But that's not good enough yet. The orbit may have the right average distance, but it may still be very eccentric, ranging from close-in to way-out in the course of 24 hours. If that's the case, then it will move faster when it's closer in, and slower when it's farther out. Watching it from the earth, it'll appear to move back and forth like a pendulum, returning to the same position every 24 hours but making a complete left-right swing every day. This still wouldn't be useful for stationary ground-based dish antennas. So another restriction on the orbit is that it must not only be at the correct average distance, but it must also be very close to a circular shape, so that the satellite's speed in the orbit is nearly constant. And there's yet one more requirement that the orbit has to satisfy. Consider this in your imagination: There can't be an orbit where the satellite circulates over, say, a little 20-mile circle around the North Pole. A satellite orbit has to revolve around the "whole earth", which is a clunky way of saying that the center of the earth has to be in the plane of the orbit. The orbit can "incline" as much as you want ... the satellite can stay over the equator all the time, or swing from North pole to South pole and back again, but the center of the orbit always has to be at the center of the earth. Now you can see the final requirement for a communications satellite: If the orbit is inclined to the equator, then the satellite will appear to swing above and below its average location in the sky every 24 hours, which also makes it hard for a stationary antenna on the ground. The orbit has to be oriented at 'zero inclination', meaning it lies directly above the equator at every point. Now, finally, with a nearly circular, equatorial orbit, of exactly the right size, the satellite appears motionless in the sky, and all those little 18-inch TV dishes on the neighborhood rooftops can be pointed once at the satellite and never need to move. A satellite in this orbit is not only "geosynchronous" (24-hour orbital period), but also "geostationary" ... motionless relative to a point on the earth.
What kind of orbit are observation satellites usually placed in?
You mean Earth observation satellites, and the answer is near-Polar low-Earth orbits. This means that as the satellite orbits from above one pole to the other, the Earth turns beneath it, and the satellite passes over the Equator, and every other point on its orbit, at a different place on each successive orbit. In this way, after enough orbits, it can view the whole Earth. Earth observation satellites are placed in low-Earth orbit because (a) they travel faster over the ground at lower altitude and (b) being closer to the ground, their telescopes do not need to be so powerful to achieve a given spatial resolution. Military observation, or spy, satellites, are often placed in a high parking orbit until they are needed, whereupon they are placed into a highly elliptical orbit to allow them to come very close to Earth (and hence see it with great detail) over the region of interest.
What kind of satellite is on the moon and orbits Earth?
The moon IS a satellite that orbits earth
What is the best kind of gun?
There is no ONE "best kind of gun". Not for military, target, hunting, or defense. Different guns are made to meet different needs.
Can you see a person in his house via satellite?
no you cannot. you can only see a person from a satellite if that person is outside. But who knows what kind of unknown technology they have.AdditionallySatellites are in earth orbit looking downwards to the planet surface so the house would typically have to have a transparent roof or a person standing on their roof to be seen.
What kind of an orbit is use by direct tv satellites?
Geosynchronous Orbit
