- Problem 2. Satellite orbits. The geostationary orbit is a unique circular orbit above the equator of a planet, for which the orbital period is equal to the rotation period of the planet. For Earth, the geostationary orbit is 4.22 x 104 km from the centre of the Earth. The Earth rotates in 23 hours and 56 minutes. a) A failed satellite, whose apogee distance is at Earth's geostationary orbit, has only half the required orbital speed of a geostationary satellite at apogee. Calculate the perigee distance of the orbit of this failed satellite. b) If another planet has twice the size of Earth and the same average density as Earth, while rotating in the same amount of time, calculate the radius of the geostationary orbit for this planet.Pls find the Question attachedAn artificial satellite circles the Earth in a circular orbit at a location where the acceleration due to gravity is 5.42 m/s.
