What are the Geostationary Satellite ?

1.	What are the Geostationary Satellite ?
Answer» The satellite which appears stationary relative to earth is called geostationary or geosynchronous satellite, communication satellite. A geostationary satellite always stays over the same place above the earth. The orbit of a geostationary satellite is known as the parking orbit. (i) It should revolve in an orbit concentric and coplanar with the equatorial plane. (ii) It sense of rotation should be same as that of earth. (iii) Its period of revolution around the earth should be same as that of earth. (iv) Height of geostationary satellite from the surface of earth h = 6R = 36000 km. (v) Orbital velocity v = 3.08 km/sec. (vi) Angular momentum of satellite depend on both the mass of orbiting and planet as well as the radius of orbit.

Answer»

The satellite which appears stationary relative to earth is called geostationary or geosynchronous satellite, communication satellite.

A geostationary satellite always stays over the same place above the earth. The orbit of a geostationary satellite is known as the parking orbit.

(i) It should revolve in an orbit concentric and coplanar with the equatorial plane.

(ii) It sense of rotation should be same as that of earth.

(iii) Its period of revolution around the earth should be same as that of earth.

(iv) Height of geostationary satellite from the surface of earth h = 6R = 36000 km.

(v) Orbital velocity v = 3.08 km/sec.

(vi) Angular momentum of satellite depend on both the mass of orbiting and planet as well as the radius of orbit.

A star 2.5 times the mass of the sun and collapsed to a size of 42 km rotates with a speed of 1.2 rev. per second. (Extremely compact stars of this kind are known as neutron stars. Certain stellar objects called pulsars belong to this category). Will an object placed on its equator remain stuck to its surface due to gravity? (mass of the sun = 2 × 1030 kg).
