  1. Which of the following is not true for Geostationary Satellite?
    1. Its time period is 24 hrs
    2. Its angular speed is equal to that of earth about its own axis
    3. It is fixed in space
    4. It revolves from west to east over the equator
Correct Option: C

A geosynchronous satellite is a satellite in geosynchronous orbit, with an orbital period the same as the Earth’s rotation period. Such a satellite returns to the same position in the sky after each sidereal day, and over the course of a day traces out a path in the sky that is typically some form of analemma. A geostationary orbit, or Geostationary Earth Orbit (GEO), is a circular orbit 35,786 kilometres above the Earth’s equator and following the direction of the Earth’s rotation. An object in such an orbit has an orbital period equal to the Earth’s rotational period (one sidereal day), and thus appears motionless, at a fixed position in the sky, to ground observers.
