What are the conditions necessary for a satellite to appear stationary? What is the direction of rotation of a geostationary satellite?

(N/A) The conditions necessary for a satellite to appear stationary are:
$1)$ The satellite must be in a circular orbit in the equatorial plane of the Earth.
$2)$ Its orbital time period of revolution must be exactly $24$ hours.
$3)$ The satellite must revolve in the same direction as the Earth,i.e.,from west to east.
$4)$ It must be at a height of approximately $36,000 \ km$ above the Earth's equator.
The direction of rotation of a geostationary satellite is from west to east,which is the same as the rotation of the Earth about its axis.
