What is a satellite? Give its types and uses.

(N/A) body revolving around a planet in the direction of the planet's revolution is called a satellite.
The motion of a satellite is very similar to the motion of planets around the sun; hence,$Kepler's$ laws of planetary motion are equally applicable to them.
Their orbits around the earth are circular or elliptic.
There are two types of satellites:
$(i)$ Natural satellite: The moon is the natural satellite of the earth with a time period of approximately $27.3$ days. It is equal to the rotational period of the moon about its own axis. The planet Jupiter has many satellites.
$(ii)$ Artificial satellite: The first artificial satellite made by mankind was $Sputnik$,put into orbit around the earth by Russian scientists in $1957$. India ($19$ April $1975$) also successfully launched '$Aryabhatta$' and the '$INSAT$' series of satellites.
Satellites are used for scientific research,engineering,communication,weather forecasting,spying,military operations,geophysics,and meteorology.
