Question

Explain equatorial and polar orbits of artificial satellites.Answer the given question in brief.

Answer 1

a) $\textbf{Equatorial orbit}$: The orbit which is parallel to the equator are known as equatorial orbit.
Thus, satellite rotates in an orbit directly above the equator of Earth.

b) Polar orbit: The orbitwhich is parallel to the meridian is known as polar orbits or the orbit which is perpendicular upon equator orbit is known as Polar orbit .

Satellites are having an inclination of near 90° from the equator. This allows the satellite to see virtually every part of the earth as the
earth rotates underneath it.
