Question

what is the period of revolution of Polar satellite orbiting close to the surface of Earth​

Answer 1

The period of revolution of Polar satellite orbiting close to the surface of Earth​ is around 100 minutes.

• A polar circle is one in which a satellite goes above or almost above the two shafts of the body being circled (normally a planet, for example, the Earth, yet conceivably another body, for example, the Moon or Sun) on every upset.
• Hence has a tendency of (or extremely near) 90 degrees to the body's equator. A satellite in a polar circle will ignore the equator at an alternate longitude on every one of its circles. Regularly utilized heights are somewhere in the range of 700 and 800 km, delivering an orbital time of around 100 minutes
