SOLAR SYSTEM

Detailed explanation-1: -Geostationary satellite is one of the artificial satellites, which revolves around Earth’s equator above 22, 236 miles in a geostationary orbit. It has an orbital period equal to Earth’s rotational period of 23 hours and 56 minutes, which is about one day on earth.

Detailed explanation-2: -The time period of a geostationary satellite at a height 36000 km, is 24 h. A spy satellite orbits very close to earth surface (R=6400 km).

Detailed explanation-3: -The period of a geostationary satellite is a sidereal day not a solar day, and that’s why it too is 3.9 minutes shorter than a solar day.

Detailed explanation-4: -The time period of an artificial satellite in a circular orbit of radius R is 2 days and its orbital velocity is v0. If time period of another satellite in a circular orbit is 16 days then. No worries!
