If the satellite appears to remain motionless over one spot on the earth, then I don't
need to know the radius or anything else about orbital mechanics to calculate its period.
It had better be equal to the earth's rotation period of 23hours 56minutes and about 4 seconds.

∙ 14y agoWe'll assume that the number given for the orbital radius is in meters.
The circumference of the orbit is [ pi D ] = [ 2 pi R ] = [ 8.46 x 107 pi ] = 2.6578 x 108 meters (rounded).
The orbital period = earth's rotation period = 23hours 56minutes 4seconds = 86,164 seconds (rounded)
Speed in orbit = (distance) / (time) = 2.6578 x 108 / 86,164 = 3,084.6 meters per second (rounded)

What is a geo synchronus satellite?
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
What is satellite orbital spacing?
orbital spacing is the satellite spacing between the satellites orbiting in same frequency band
What type of orbit can orbit earth and have a orbital period equal to the rotation period of earth?
The term you are likely looking for is "Geosynchronous Orbit"Any orbit with a semi-major axis of about 22,000 miles has an orbital period of 24 hours.If the orbit is circular, then the satellite is always at the same longitude,but oscillates north and south every day.If the orbit is in the plane of earth's equator, then the satellite appears stationaryover one place on the earth's surface.A good example is any of the satellites that send TV to those little dishesmounted on everyone's garage.
The time period of a geostationary satellite is?
If a satellite is in geosynchronous orbit, it will take the satellite 24 hours, a day, to orbit the Earth once. This is so because geosynchronous orbit is when a satellite orbit the Earth at such a time, that is is over the Earth at all times.
What is the size of the moon for Venus'?
Venus does not have a natural satellite, though the asteroid 2002 VE68 presently maintains a quasi-orbital relationship with it.
What is a geo synchronus satellite?
A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth's rotation period.
Does dbs also known as direct broadcast satellite such as directv and dishtv orbit in a geosynchronous orbit and why?
YESSatellites in geostationary orbit have an orbital period that is exactly the same as the Earth's rotational period. This means that looking from Earth the satellite appears to be stationary in the sky. This means that satellite dishes can be fixed (or static) and do not require complex motorised mounts to follow the satellite across the sky. Also it means that the satellite does not rise or set and so is never hidden from view below the horizon.
What is geosatelite?
A geostationary satellite is an earth-orbiting satellite, placed at an altitude of approximately 35,800 kilometers (22,300 miles) directly over the equator, that revolves in the same direction the earth rotates (west to east). A geosynchronous satellite is a satellite whose orbital track on the Earth repeats regularly over points on the Earth over time.
What is special about a geosynchronous satellite?
Its stable orbit and velocity is exactly enough to keep up with Earth's rotation. From Earth's surface, looking up, a geosynchronous satellite would appear not to move; essentially keeping it overhead, and making it permanaently available to bounce communication / TV signals off.Related Information:Moving from the earth outwards, only one orbital velocity will sustain stable orbit, at one particular radius.
What are the orbital communications satellites are placed in called?
Geosynchronous orbit? or Low Earth Orbit?
What would be the effect on the orbital velocity of satellite if mass of satellite is double?
Its mass won't affect the orbital velocity.
What is satellite orbital spacing?
orbital spacing is the satellite spacing between the satellites orbiting in same frequency band
What is polar orbit and geo-stationary orbit?
A satellite in polar orbit passes over the poles.A geosynchronous orbit follows the equator and at such an altitude its orbital period is one day long and remains in the same position relative to the ground.
What does perturbation do to a satellite?
it affect the path and orbital velocity of satellite due to gravitation pull
Is the critical velocity equal to orbital velocity of satellite?
Balance of force of gravity by centripetal forceYes, for any given orbital radius (r) only one velocity will give stable orbit, this is called the critical velocity.Pick your orbital radius and satellite mass (m)Use Gmm / r2 to calculate gravitational force (f),then find velocity from : v = sq root ( (r * f ) / m)
Why does it take 28 days for the moon to circle the earth?
Because its distance from Earth is roughly 238,000 miles. The time it takes a satellite body to revolve around its central body is completely determined by the shape and size of its orbit, and has nothing to do with the size or mass of the satellite. In the case of the Earth as the central body ... -- satellites at an orbital distance of 350 km, like the International Space Station, take about 90 minutes to revolve; -- satellites at an orbital distance of about 22,000 miles are 'geosynchronous' ... they take 24 hours to revolve; -- satellites at an orbital distance of 238,000 miles, like the moon, take 27.32 days to revolve.
