Satellite orbital velocity
Satellite is an object which is moving around the Earth. There are two types of satellite one is natural satellite made by nature (Moon) and other is artificial satellite which is made by men.
One important point i want to make it clear here from childhood you learn that every planets move around the Sun, Moon moves around the Earth, even any picture of solar system shows all planet moves around the Sun including Earth.
But you will shock, When i will tell you this is technically wrong all planet and Moon does not moves around the Sun and Earth.
Then you will ask me if all the planet does not moves around the Sun, which is that body around it all planet moves. And your next question will be if it is wrong then why teach like this wrong concept in book ?
Well actually books and pictures shows all planets moves around the Sun is correct, so that you can easily understand the solar system behavior without knowing the technical point.
Now here you will learn around which all planet moves and even Sun moves around which,
and also why do you teaches that all planet moves around the Sun ?
Planets and Stars moves around the common centre of mass, This common centre of mass is also known as barycenter to understand barycenter you must know centre of mass you can refer my previous post center of mass concept.
Centre of mass is that point at which whole mass of the body or system lies at that point, means body is balanced, sometimes it can lies outside the body, some time between two masses and sometimes near the heavier mass depends upon the mass quantity and its shape and size, for more details refer above link.
