The period of the earth as it travels around the sun is one year.
Time period of a satellite revolving earth is given as t height at which it orbits the earth is then.
If the point of projection is apogee and in the orbit the satellite comes closer to the earth with its perigee point lying at 180o.
You can calculate the speed of a satellite around an object using the equation.
The semi synchronous orbit and the molniya orbit.
If the horizontal velocity imparted to the satellite is less than critical velocity vc then the satellite moves in a long elliptical orbit with the centre of the earth as the further focus.
The period of a satellite is the time it takes it to make one full orbit around an object.
Radius of the orbit of the earth r e 1 5 10 8 km 1 5 10 11 m radius of the orbit of the mars r m 2 5 10 11 m time period of earth t e.
The mean angular velocity of the earth around the sun is 1 per day.
Case 1 v h v c.
In how many years the mars completes its one revolution.
The semi synchronous orbit is a near circular orbit low eccentricity 26 560 kilometers from the center of the earth about 20 200 kilometers above the surface.
Two medium earth orbits are notable.
T 2πr v c 2 x 3 142 x 6400 7 931 5071 s.
T 5071 3600 1 408 h.
If you know the satellite s speed and the radius at which it orbits you can figure out its period.
The time period of a satellite orbiting around the earth is given by.
The speed of the satellite is 7 931 km s and the time of revolution of the satellite is 1 408 h.
Thus the radius of its orbit is approximately thirty times that of the earth.
