First, it is necessary to understand the concept of escape velocity.
The <u>escape velocity</u> is the <em>minimum speed with which any object needs to be launched to move indefinitely away from a more massive body or system to which only the gravitational force links it.
</em>
In this sense, each planet and body of the solar system has an escape velocity with which if an object is launched, it can escape the gravitational attraction of that planet. In the case of Earth it is approximately
.
