Which vehicle is used to put more satellite to orbit?

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.


Does orbit change depending in how far it is from the sun?

Yes, things farther from the sun orbit more slowly.


Does the satellite requires power to revolve around the earth?

No. Once the satellite is placed in orbit, its momentum will keep it orbiting along its original path - more of less. "More or less" means: 1. The satellite may need minute adjustments to its position, so that it can photograph its intended targets (stars/planets, the earth), or can keep in contact with its intended radio/television/mobile phone services, and 2. A satellite's orbit will slowly decay, and the satellite would eventually come into the outer atmosphere, begin to slow down, and burn up as its orbit brought it into denser air. For both these reasons, satellites may use small "positioning" thrusters to steer and to regain orbital speed.


A satellite is 200 miles above the earth It has a mass of 150 kg If the mass of the satellite were tripled?

You don't really have a question here. If the satellite is in orbit, the mass is essentially irrelevant; it wouldn't change the speed of the orbit or the altitude. A larger satellite mass WOULD HAVE required more fuel and more energy to LAUNCH it, but once in orbit, it will stay there. The only exception would be an exceptionally large, light satellite. There is still some minuscule traces of atmosphere at 200 miles, and a large, light satellite would be slowed by air friction much more than a small dense satellite would. This is what caused the "ECHO" satellite - essentially a silvered mylar balloon inflated in orbit as a primitive reflector comsat - to deorbit.


How far above the earth is geostationary orbit?

Geostationary satellites are in an orbit that's 22,282 mi (35,786 km) above the surface of the Earth. For more on Geostationary satellite orbits, visit http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx


Who calculated that more distant planets orbit the sun more slowly?

Johannes Kepler


What would happen if the path of a satellite if its orbit was tilted more?

If its orbit is tilted relative to the equator,it will move over different parts of the earth.


What is the path followed by a celestial body or satellite as it revolves around a more massive object?

Its orbit


What is the path followed by a celestial body or satellite as it revolves around a more massive oject?

That is its orbit.


Can an object be a satellite and orbit another object at the same time?

Yes. The whole idea of being a satellite is that the object orbits another object. If you mean 'can a satellite orbit more than one object', then the answer is also yes. Objects orbiting binary stars would be an example of this.


What can you say about the orbit time of a satellite in lower orbit then geostationary one?

Its closer to the earth. Can say much more without know the velocity of the satellites
