this is if it is not a geostationary orbit, in which case it is always in the same place relative to earth.
imagine a circle of radius 42250km+radius of earth(6,356km). it's perimeter is
2 x pi x 48606km = satellite's journey.
then think of a really fast speed, which is the speed the satellite is moving at.
divide the distance by speed and you have the time of one orbit
However, by the height being 42250
, it makes me think the satellite is a geostationary satellite and so it would take 24 hours moving at approximately 12725 kmph
does that answer your question?
The time it takes for a satellite to complete one full orbit around the Earth, known as its orbital period, can vary depending on the altitude of the satellite. On average, a satellite in low Earth orbit (LEO) typically takes about 90 minutes to complete one orbit, while a geostationary satellite orbits the Earth every 24 hours.
5 hours
No Sputniks are still in orbit. When they were, the period of an orbit was about 88 minutes.
Sputnik was actually the first artificial Earth satellite launched by the Soviet Union in 1957. It did not travel to Mars, but instead orbited Earth. It took the spacecraft about 98 minutes 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.

About an hour.

Its called a geostationary satellite. Its quite far out, meaning its 24 hour orbit is quite long when compared with satellites closer in to earth. Is appears stationary in our skies, in the same spot throughout its orbit. This makes it a lot easier to track, a fixed dish can be used.
Sputnik was the first satellite to orbit the Earth. It was Russian and transmitted a radio signal. It is possible that a earlier satellite could be in orbit, without any communications this would be the same as a cannon shell etc. So long as an object can reach orbit it will constantly drop towards the planet and because the planet is round the object will rotate around being pulled by gravity
A Landsat satellite takes around 16 days to scan the entire Earth's surface. This is due to its polar orbit and repeat cycle for complete coverage of the globe.
You can put it in any orbit you like, as long as the orbit follows a few simple rules: -- It must be elliptical. (A circle is an ellipse too.) -- One focus of the ellipse, or the center of a circular orbit, must be the center of the earth. -- No part of the orbit can dip into the atmosphere; if it does, then your artificial satellite and its orbit won't last long.
A satellite in Geosychronous Earth Orbit (GEO) orbits the Earth in the same time period that the Earth spins, so the satellite appears to be stationary over one spot above the Earth's equator. It's always looking down at the same area of the Earth. A satellite in a polar orbit will pass quickly over any one spot on Earth and keep going. It can't watch the same area for a long period. Depending on the altitude of the orbit, it may take days or weeks to pass over the same area again. However, polar orbits are typically much lower, permitting a much higher resolution image. This is very important for photo imagery, but not so much for weather.
Satellite orbit the Earth at different altitudes. A good overview of Low Earth Orbit, Medium Earth Orbit and Geostationary Orbit can be found here: http://www.idirect.net/Company/Satellite-Basics/How-Satellite-Works.aspx
